Unhidden | Tribute - C700P - a Zeuligan mod


Recommended Posts

Ever since the first Cosmos I have had a dream to own that case. When the C700P was released I knew I HAD to own it and mod it. Making it extra special for me to enter the CMWS19, both on the 10th anniversary, but also with this amazing tower. 



The idea of the mod is to pay tribute to the case. Modding it, but still leave as untouched as possible. I also want to expose 100% of the case. To do that I will spend as much time on the backside as the frontside. To crown that idea, I got a 2nd window to ensure the backside is Unhidden :grin:

It will be a custom water cooling hard tube setup with dual loops. I also plan to 3D print parts

I want to thank my sponsors for this project
Coolermaster Sweden / Nordics


And with continuous support of:

Just look at that beautiful case. Will be hard to mod this amazing thing and still keep it as clean as possible. For me, this entire mod is about taking away enough to get more attention to the case, but enough to make it a real mod. Find that balance will be the big challenge. 







Thanks to amazing support from Coolermaster this amazing platinum PSU will be the beating heart. I have a plan to get the PSU visible, but still use a shroud. To ensure every single product in this mod will be unhidden and tributed. 





Any big project needs it fans. Again lucky with the support, I got these amazing Masterfan Pro 120 to be the showcase of the mod. I plan to make them visible in a very special way. Based on an idea I got from a previous mod. 





It is almost breathtaking to watch all this power from Alphacool. So much water cooling godness going into one case. Almost hard to believe how I will fit it all. 









Happy with this first evening. Took a few hours to rig the photo studio and take pictures of all the products. Then carefully started to pick the Coolmaster Cosmos C700P apart. I'm left with the frame and have a great starting point for tomorrows full day of modding. Let the game beging. 
Still a little creative panic, so much to do in so little time. Less then 4 weeks to do a full mod from scratch. Haven't even started Fusion 360 for the 3D prints yet...
Yes, I can feel the pressure...

First day of modding. Super excited. Started at 6am with breakfast and a long session in Fusion 360. Can't say I felt bad with a Coolermaster T-shirt and a Alphacool coffeemug in my hand. First thing was to start 3D-printing to maximize work hours. Print while doing other stuff. 






This is just a small piece, printed on my Ultra fast print profile, to make sure I had measurements correct. Had to make one adjustment and run it again. The idea is to print the entire backside "plate" with honeycomb mesh patter. I also need a bracket to hold the custom motherboard plate. Visible as a 20mm vertical edge on the above print. 







After some hours to many I had decided on a placement for my dual Alphacool Eispumpe with plexi RGB top. I will need to create a custom bracket to hold both the pumps, but had already accepted that. 





Unboxed the Alphacool radiators and Coolermaster fans and put it all together. 






One rad in the front and one at the top. Pretty much standard. Also onboxed the Coolermaster V1000 Platinum PSU and fitted that. I want all the components mounted as early as possible, just to ensure I have enough room and that they end up in the right place. Important for the next few days. No room for even 1mm off and I do all work by hand. Next couple of updates will hopefully show what I'm refering to, depending on the speed of my progress. 



After about an hour in Fusion 360 I had an working model of the pump brackets. Decided to 3D print them. If they wont end up sturdy enough I have designed them in a way so I can just slide in an aluminum bar at the back wall as it is exactly 20mm in the inner measurement. 


Almost 3h on the bed, even with the uggly fast print profile, but still happy. Had to make 2 adjustments to perfectly align the bottom holes with the frame of the case. 


Ending this modding day at 21pm. Long day. Not that much physical to show for, but super happy. I have a pretty good idea how to proceed from here and I have discarded almost 10 concepts for the shroud and motherboard plate. Think I have it down for tomorrow. 

Best thing with 3D printing parts, is that the printer runs while I sleep. I got a 10h print (the pump bracket) loaded. Very curious how it will turn out tomorrow morning.

Waking up to a successful print is a great feeling. Waking up to a successful print on the second day of CMWS19 is an awesome feeling. 

Happy with my pumpbracket.






Fits perfectly. Snaps in place with just a little push and will not only keep the two pumps in place, but will help keep the case more rigid as I have removed every bar and steel component from it. 




After a lot of planning, measurements, a few dummy pieces in cardboard I took out the 5mm thick acrylic that will serve as the new inside mounting wall and motherboard tray. Trimming detailed cuts on my Ryobi saw is just amazing. Love that saw. 





This is how it will fit from the backside. I'm moving the backside "wall" 40mm further into the case to make room for some backside goodies. Unhidden | Tribute ;)

Decided, as I usually try to do when I mod, to keep the case as it is. No drilling or cutting into the original case. That is my main idea. Therefor I decided to hang the wall onto the radiator frames. 





After some thought I came up with this design in Fusion 360. A snap in bracket to fit exactly into the cable cutouts of the radiator frames. 





After less than 1 hour on the print bed I got a perfect fit from start.It snaps into place from the inside of the radiator bracket. 





From the outside it shows how snug fit it is. 



Test drilled two 5mm holes 12mm apart in a scrap piece of acrylic. It worked like a charm.





Had to test with it onto the bracket and with a 5mm thick acrylic. It is just a little loose, just like I need it, as I plan to add a little more surface thickness when I do the wall finish. 



After that I still wanted to ensure the inside wall would stay in place with more then just a few plastic pins. Decided to create a little more complex piece and make use of the dual corner frame of the case. 




Came out really nice on the first print. 





Twist and snap onto the two bolt rivets of the case and then a screw from the original box and it fits perfectly. It both squeezes the wall onto the PSU bracket as well as giving the acrylic an edge to stand on. Super happy. 





Had to try the pump bracket. Only have one printed, but it is still very sturdy. 




This gives a little sneak peak into what I'm after. Had a very productive day and have a pretty good idea what to do with the PSU shroud that will be the next piece. 


Leaving this day 2 with the second pump bracket loaded into the 3D printer. In 9h I will know if it turned out as good as the first one. Slightly different design.

Day 3 was mostly Fusion concept itterations to decide on a path with the great exeption of the 2nd pump bracket. Started day forth fairly late as I had regular workday (as most of us do) but decided to start working on the front of the PSU shroud and the pump top cover. 



First piece of the printer was this concept of a bottom plate. 





Mounted the 2nd pump bracket and that plate design fits good. Time to start with the 2nd piece. My idea for this pump cover is to print it with as many flat parts as possible. Will not only make for MUCH faster print times, but should making sanding and finishing much easier. 




Second part was the corner piece of the bottom. Finish isn't great, but I try to print all concept and test parts as fast as possible. With a production piece you have to start to think about finish and print orientation. 







With that in mind I opted for this slide in / click in design for the back inside wall of the front shroud and pump cover. Just 10mm of height (for testing) but the real will be 130mm tall. 







Fits pretty good if I can say so myself. 





Next couple of hours went to make more pieces and finally trying them all together. 





Next step was starting on making the inside wall / motherboard plate fastening holes. I need the wall in it's correct location to be able to plan where to put both the motherboard and ensure I have enough room for the dual reservoirs and clearing the height of the PSU shroud. For reasons I can't disclose yet, I need the PSU shroud to be exactly 135mm in height. With that in mind, i printed some drill templates mirroring my previous snap in pins. 





I put the wall in place, snapped in the templates and made approriate holes. 





Some regular dishsoap works as lub for drilling acrylic. Slow speed on the drill and even preasure. 





After moving around the AMAZING ASUS ROG Maxium X Formula I decided on this location. It is SUPER tight. It is almost against the top fans and still only 8mm clearance at the bottom. Absolutely no room for error. 





The Alphacool reservoirs will be placed somewhere here and this is a sneak peak on how I invision the interior of the build. 





With the inside wall / motherboard plate out of the way I could move on to where I need to push work - the PSU shroud. I was previously very happy with my snap-in bracket for holding the inside wall. I decided to use the same solution for the shroud. A quick alteration in Fusion 360 and 1h print later I had to almost solid clips. 




A 3mm thread and ready to test. 



This solution is amazing. It clips in so hard that I could actually lift the case without even adding the bolt. Something I still did of course. 




130mm exactly. Super happy. The acrylic is 5mm, making it a perfect 135mm as ordered. The clips are super, will use them in the future for other mods. So easy to adjust height and then just add a shroud plate ontop. If you want the design, let me know and I can send you an .stl. 


Speaking of shroud. Here is the top of the PSU shroud before I cut it. 489mm long and 18.8mm wide (not easy to cut that exactly by hand, but managed). 


After some detail trims for the backside corner I was ready to test the design of my clips and get a first glims of the design direction of my mod. 




This is where I will end tonight. I needed to push atleast to the shroud as I have ALOT of work ahead of designing and making a GPU bracket. Fit and drill the holes for the motherboard and start to plan the loop. Got the hole backside plate to print as well. That will be atleast 30h print if not more.

  • 2 weeks later...

Spent last days with the 3D printer. Got a huge 60h print that has taking lot of time to CAD and tweak, but the first slice out of 5 is loaded as we speak. Very excited to see how it turns out. One of my main challenges with the inside wall is to design a nice loop run. I'm also a little worried with all the drilling, but only way to know, is to get it done. 




First business of the day. Place the motherboard at the right place, mark the holes and pray (no room for errors). 




9 holes later, I only had the last 2 guide bolts to add. 2,5mm drill holes, 3mm thread. Then I just put the motherboard bolts in the teeths of the Ryobi drill and screwed them in. Worked really good. 





Phu such a relief. Hard to get 9 motherboard bolts in place with just a hand drill, but managed. Happy. 





Decided to treat this rig with a new heart. 9900K was the obvious choice. 





Will be a great combo with the beautiful XPX Eisblock from Alphacool





I mounted the CPU and added the block temporarly to have the option to turn the block depending on my different choices of tube run. Also took measurements for the dual reservoirs and drilled for the brackets. Passed the point of no return. 





I find it hard to draw loops in Fusion 360. Makes it easier to test and think IRL, so I always use straws. Pulled out 2 colors to keep the two loops apart and started my design. Had a good idea what I wanted to achieve, but you never know untill it's done for real if it will work. 





GPU will be vertical and integrated in the shroud. Started with that. The CPU block and VRAM is also 4 placements I can't control, so that was next. 





This might work :) 




With this preliminary backside. Still need to add the 2nd pump (finally got shipping notice about the missing water blocks) to be 100% sure of placement. 





Converted my temporary straw design to the real thing. This needs to be right. 





A tight fit with the motherboard, but it cleared. Last problem solved. 





With a dual angled fitting in the radiator I can stack the pass throughs for that ontop of eachother. Next step is to start to do drill and bend some hard tubes. Super excited.

It is always exciting to start with bending tubes. Feels like a water cooled project moves into it's readiness face. I started bending much earlier then I usually do. Mostly due to all the pass throughs. The loop is really complicated as it is. Making all the pass throughs with hand tools, it's a real challenge. 




I bought a real drill for the occation. Expensive, but hopefully worth it. 




Made a test drill in a scrap acrylic piece and it was such a difference using this real drill. Those pass throughs will look amazing in the build. 





After mounting the wall one extra time, controlling every single measurement both once and twice I took a deap breath and started drilling (please hold, please hold)




Like a dream. I realized I will have to drill out the hole from both sides as the steps on the drill are not 5mm deep. No problem, just good to know so I don't end up with to big holes on one side. 




It's not all the holes, but this is where it starts to become even more complicated. Some holes will drive others that drive a third. The GPU will enter the shroud in the front, but will need to exit in the back. Would prefer to have the holes exactly opposite of eachother. Still very proud and happy. A lot of holes in the right places without any cracks. 





Moving on to bending. I can't say I felt like Bender. I was off my game so took two tubes untill I started to feel I had the feel for the heat, the time and the optimal radius. Bending by hand but still controlling angles when cooling. 




The first 3 went fine. They are also pretty straight forward. Dual 90 bends with one side higher. The CPU and one VRAM. The last VRAM will have a little different route so I could keep the 4 pass throughs symetrical (the VRAMS equal distance from the center CPUs). 








One, two and three. Super excited. 







Nice and parallel. Took 3 tries to get the tripple 90 bend in different planes exactly right, but can't leave a tube that isn't perfect. 





Spent another 15min with a hand file to make sure the lengths was exactly right. Hard tubes are so sexy :)


Next step will be to start with the shroud pass throughs and connect the reservoirs. Also need add the 2nd pump and work on the backside. Both the shroud part that will drive the location of the pass throughs and the last of the loop.

PSU shroud was up on the agenda. With part of the hard tubes done for the loop I need to connect the loop into the PSU shroud. More precision drilled pass throughs :)





As it was time to mount the reservoirs to make those connection I also took some photos. Love the feel of acrylic and glass. 





That's how I will mount them. Changing my straw-loop a little, but to the better. 





Two quick holes with my stepdrill and ready to continue. 





Much better. Small tubes, but enough to show some colant going into the shroud. 





Like that :)





This will be a GPU bracket that I will mount ontop of the shroud. It has both screw holes for the riser cable and below that screws for the shroud. Angles are them also fetched from the angle of the exterior of the case. Should harmonize well. 





With the bracket decided I could move on with the corner pass through from the radiator above. 







Nothing strange. A straight tube. 





Did a quick test with the PSU. This is the main reason for my previous comments about why I wanted the PSU Shroud exactly 130mm up. I need to fit the fittings :D That will go straight out to the backside. 




Spent about an hour, with elevated pulse, adding the waterblock to my 1080Ti. That will be perfect. That also passed infront of my camera.  






With the waterblock on the GPU I could make measurements for the GPU pass throughs. Thoose two will also "drive" the location of the final pass through. But first I wasn't happy with the shroud brackets or the obvious problem of adding 1kg+ of weight ontop of a thin acrylic sheet. The sag is real...







Redesigned the MB bracket from the backside and did a simular solution for the PSU. But this time also with a 45degre angle to support the upcoming "wall" for the pump enclosure. 





Added a bracket to use in the front, to support the back corner of the PSU








Just two standard case screws from the front (making it adjustable in height) and I felt I had a nice solution for the shroud. 





Made a planned update to the back bracket (that will be much bigger and include holes for GPU, PCI slots etc). It also has a vertical slot to guide the motherboard plate. As it's isn't the finished plate it's printed on prototype profile (fast) making it look bad, but modding quicker. 





Much better. That secures the PSU shroud plate, but doesn't take care of the sag. 





It's not a permanent solution, but will take care of the support of the GPU for now. 





12h later and after 2h of sanding I had a new GPU bracket. This time with an integrated holder for the lower part of the PCI bracket. It's not finished, only sanded with 240, 320 and 400 at this point, but already smooth :)



Compared to no sanding. 





With the real GPU bracket I could ensure I had the right location and placement compared to the back. 




Testfitted the riser cable, added the GPU and took measurements for the final pass through holes. 





Voila! Starting to feel like a real build. 14 out of the 16 pass throughs hand drilled and in the right place. Tomorrow I will continue to finish the backside holes and bend some tubes.

Work continued with the front part of the PSU shroud and the specifically the pump cover. 




I started testing different design ideas and print solutions. Knew what I wanted as an end result, but not sure of the road to it. After some time I felt I had a solid solution. 







This is how I want to show the unhide the pump, but still keep it as clean as possible. First print is a faster prototype profile .





Just like I wanted it. The pump is what draws attention, but still keep it classical with a PSU shroud. I felt I had to make some change as it felt a little to flat and boring. 







After going back to the original shroud from Cooler Master and it's angled design with a more narrow top I had my inspiration and tribute. I cut my shroud open after the pump cover and I felt I had made a great improvement. Now the pump is even more in focus and the over all design is less boxy. 







I only had one real problem left. I can't hide the beautiful PSU behind a shroud wall. It's both wrong and wouldn't be true to my original concept - Unhidden | Tribute. Had an idea and made a design in Fusion and loaded the printer. 





That will work. The rhombus  shape with the design of also making it smaller the further in it goes is a real eye catcher towards the logo and the PSU. It also brakes up the flat surface of the PSU shroud in balance to the pump cover. Super happy. 







Took some measurements and cut the front part of the shroud open after the rhombus  shape. 





The last thing left to fix on the front of the PSU shroud was to make room for the head of the screw I need to keep my PSU brackets in place.







I had a real drill bit that I loaded into my drill driver and tried to keep both a steady hand and not go to deep and cut through. Think I did really good :)




That's more like it. Next step will be to focus on the backside wall and the backside of the PSU shroud.

With the backside out (again) I could start with cutting hole for the second pump. 




There it is. Measure twice, cut once...





That's more like it. Can't hide such a beauty. Also want the symetry with the front as well as making the backside as rich and alive as the front. Everything unhidden. 





Re-mounted (again) the wall and got ready to connect the backside pass throughs. 





Two equal bends. One to the top and one to the bottom. 





I played around with the top connection and after a few different options I opted for the short 45deg bend to keep it as parallel as possible, but also frame the compartement above the pump (I got plans for that). 





Added the motherboard again, to take measurements for all the cables, 24pin, 8pin, front I/O panel, SSD's etc, but the real fun will be the ATX lines. 





With the GPU sorted I could finally add the last and 16th (yeah) pass through. 





That will be a scary hole to make. So close to the pass throughs and the last one. Don't want to brake it now...







I ended up cutting a really small line and spent 2h with the hand file. Not only am I afraid to brake the main wall plate, but I also need a 0,5mm tollerance hole (with a hand tool). Only way I know how to do that is to cut small and expend partially until good. 





That printed bracket with a small edge to clamp it together will be perfect. 




One of the last bends. I keep reusing the same 90 bends to keep the real one scratch free. That's why there is only one pipe done at a time.





With the last bend in place I could take some measurements on cable comb placement and with that the route of the ATX cables. Had a working plan. 





I always use MDPC-X and it was very heartwarming to get this Zeuligan Edition sent in the mail for CMWS <3. I also sleave my cables in place to make sure I get the perfect fit (hence only pins in one end). Therefor I have two dummy cables I use to take measurements before I work with the real one. 








Decided to opt for a straight vertical 8 docking it into the 24. 16 cables wide run into the top of the psu shroud lid in the back.
