This is my 4k tv connected pc that I use to play steam games. It was my first itx build (done in 2012.) I recently redid the cable management for the 3rd time, and I got the idea to hide the xbox 360 wireless receiver inside from someone else who posted here. Unfortunately, I don't have the original post of the person who came up with that idea, but props to the original creator (very clever idea!) Everything is pretty standard, the only customization I did was replace the h80i's stock fans with Noctuas because the thing sounded like a jet engine at times, the noctuas drop the sound by a few db's at full load so I'm very happy with it (haven't really benched the temps though, but I've heard good things about em so I trust it.)
I've managed to overclock the cpu at 4.3ghz with pretty good temps, I could go higher but it got a little too warm for my liking. Currently the cpu idles at around 30c and on load I think it was somewhere around 60c, so I'm very content with that. (though those benchmarks were prior to the Noctua swaps.)
Future: Seeing as how I just upgraded to the gtx 980 ti sometime last year, I am kind of wishing I had waited for the Pascal cards, but I'm still really happy with what I've got. Maybe another year or two down the line I'll put the 980ti in my main comp and swap out a better gpu since this is the only comp connected to a 4k display.
Other thoughts: This is totally a sleeper comp because the case has nothing flashy to show off the parts. I debadged the cooler master logo on the front panel (but there's this weird indent and shape on the actual grille thing, so you can see where the badge originally fit. One of these days I'll get something to cover that.)
