Update - 8/5/15 -
Finally got everything figured out! It's not the most elegant solution in the world, but I think it might work!
If anyone has seen me posting in random threads asking for help you know what has set me back for the last week on continuing the build. My original design of a radiator in the bottom is NOT going to work how I wanted it to. The problem is that when I started fitting everything in the build I realized that the spacing I had thought I had wasn't really there. I'd need to squeeze the radiator into a 26mm space EXACTLY and I couldnt figure out how to make it work. But I found the answer after looking through a lot of different threads and other forums (even *gasp* reddit) and a lot of people gave me some great ideas. The one that seems to be the most likely candidate is a stacked radiator design. Here is how we are going to get this to work:
We are going to trim the casing of the radiator and the fans a bit to make the fans sit flusher and save space. Loop isn't set in stone, when I get everything in it we will try and see the easiest and cleanist way to run the loop.
Im still playing with the idea of an ATX psu in the case, but If I do the connectors on the board are going to need to be changed (24 pin) either with an adapter or by desoldering the connector. If we go ATX I'm throwing in 2x Fury's. If we go SFX them in going GTX980's. I'm dropping the front expansion with the original psu completely. It just didnt look nice, so now it comes to "How much power can I fit in here" as the deciding factor for the GPU's.
Package is getting here Friday! My excitement level is unreal at this point.
