Always wanted to post my setup and I think it's about time to do it. Will probably move out in a couple of months, so things will change drastically, but I'm so happy with my current one so why not sharing?
(living room)
I used to have both my computer and the rest of the gaming stuff in the same area, but decided to separate work with leisure, so I moved PC+monitors to another room. I am currently streaming all my PC gaming to the TV via Steam link (hidden behind the TV, alongside Wii U's gamepad).
The TV I'm using is a Panasonic 42ST60. PS3+4 are hooked up to my Logitech z906, while the Wii U and the Steam link are hooked up to my stereo amp (Cambridge Audio CX60) via TV audio pass-through. I wish there was a way to have 5.1 surround sound for my PC gaming, alas it's not possible at the moment.

i5-2500k @4.6 GHz
Asrock Z77 Extreme 3
Corsair XMS3 8GB RAM
MSI GTX 970 Gaming 4G
Samsung 840 EVO 250GB
Western Digital Blue 500GB

Most of my games are back in my home country. The plan is to transform my attic into a game room, but that's gonna take ages given that I hardly ever go back there (twice or thrice per year).
