First computer build. Use it mostlly for general computer use, with some gaming on the side. Have it hooked up to a 24" Insignia 1080p TV. Wireless Logitech keyboard and JETech mouse (Kinda meh). Replaces my laptop which I was getting sick of. Eventually(Maybe), I'll get around to tidying up the cables. HDD isn't connected yet, since the Mobo didn't come with enough SATA cables. Also, wish I hadn't installed the Hyper 212 Evo with the Cooler Master logo upside down. I think I used a tad more thermal paste than I initially wanted to use, and installing the heatsink was a little more trouble than I expected, but otherwise everything came out great.
Update: 1/28/2015 Connected HDD, since my 120GB SSD was getting kind of full. While I was at it, I got around to tidying up the inside cables. From the front, the inside looks pretty nice now. The back(Which thankfully nobody can see), is a complete nightmare of cables though. Also, yesterday I overclocked the CPU to 4.6 GHz instead of the stock 3.9 GHz.
Update: R9 390 installed in there now, and of course I needed to get a beefier PSU as well. I'm also using a decent wired mechanical keyboard and wired mouse now.
