I built this computer primarily for gaming. This is my third personal build and by far the best looking and most high-end one.
I wanted to have as many high-end components to just splurge on my best ever computer build yet, but still have a small reasonably small case. The best looking small-ish case at the moment is the Fractal Design Meshify C Mini, it's beautiful.
I had many problems, because I wanted to pack this case full of goodies. I have around 5mm of space between the GPU and the radiator, which is mounted to the front, because a 280mm radiator cannot fit up top. I had to mount the radiator fans outside of the case and cut a bit of plastic of the frontpanel to make the fans fit (the fans push the mesh section a bit so there is small bulge).
I added two Corsair LL140 fans to light up the inside a bit. Added the Corsair RGB ligthstrip as well. Bought some white PSU cable extensions from CableMod and love 'em, they really tie this build together. I am quite pleased with the aesthetic and performance of this build.
