NR200 top and bottom radiator mounts

These are the .stl files I made two years ago to build a custom water cooling loop into my current PC. For those of you familiar with the Cooler Master NR200 case, you'll know it is a nice mini-ITX case and it gives you quite much flexibility to put things as you like.

However, it does have some limitations, which of course I found out when I decided to mount dual radiators in this case. So I set myself to work, but after seeing other people's project, I realized most (all?) of them involved cutting, drilling or otherwise modifying the case, which I didn't want. I wanted to mod it in a way that could be reverted. So, let me explain how these pieces work:

• The bottom adaptors consists of just a pair of brackets that attach to one end of a 280 mm readiator each one, then it goes on the case's bottom grill, and the holes align with the grills'. Just a note: in order to be able to fast the brackets to the grill, you must first put 4 nuts (2 for each bracket) in the hexagonal insets prepared for that. I have used M3 nuts. Additional note: to add fans, just bolt them on top of the radiator, using the radiator's own holes.
• The top adaptor consists of 2 different parts:
  • First, there are 3 brackets that latch to the case's frame, which help offset the mounts for 120 mm fans/radiators to the exterior side of the case, instead of having them centered (as with the standard top plastic mount). In my build, these brackets were used for the fans, not for the radiator, cause I needed clearance to install the hard tubing. The 
  • Then there is another small offset adaptor, of which you'd have to use 8. Each of these adaptors holds one M3 nut (8 nuts in total), and goes between the top 120 mm fans and the 240 mm radiator. They help offset the radiator even more to the exterior side of the case, so it sits almost flush with the top frame of the case.
• How to mount the top adaptor: 
  • First, set the nuts in all 8 of the offset adaptors (you could probably get away with just 4, but I used all the holes). This is most easily done by using a soldering iron to heat the nuts and push them into place. The hot metal will melt the plastic around and helping settling itself.
  • Mount the 3 in place. The place is top of the case's frame. They go between the two lateral frames of the case, with the “clips” facing upwards, and you have to slightly bend them to lock them in place. It may seem flimsy, but when you attach the fans to them, they won't be able to flex and this will confere them the needed rigidity.
  • Mount the offset adaptors onto the radiator, but use the holes WITHOUT nuts (each adaptor has 2 holes). The nuts are used in the next step to bolt the adapter, fan and case's frame all together.
  • This step involves some manual aligning. You will need to put the two fans you'll be using on top of the offset adaptors and align the holes more or less, then take all the precarious assembly and put it in its place, aligned with the holes of the already mounted 3 top brackets. Hold it with something (probably your left hand) while you try to bolt it with your free hand(s).

And that's all. Easier said than done, believe me. Be open to changes and adjustments, the tolerances for my build were so tight I have to mount and unmount it in a certain order, or the components won't fit. And I apologize for the lack of images. I did want to include some, but the only documentation I have is in an old reddit post that was an earli WIP phase, and doesn't show the pieces I finally used. I just took a couple photos, but I promess, next time I have to tinker with my PC, I will make sure that I can take some photos to properly illustrate the steps to follow :)

Oh, I also included two additional pieces that I used as cover and pump mount, they go over the bottom 140 mm fans. And just not to leave anyone hanging, I wanted to include the FreeCAD .FCStd files, but hell yeah, printables.com says that “unsopported file type”. Bummer.
