What I built this PC to do: play EVE Online, some modern games like CSGO, Space Engineers, Civ V, etc, some classics like Baldurs Gate, System Shock 2, Neverwinter Nights, ROMs (primarily through RetroArch) some java stuff like Minecraft, some web stuff, and that's mostly it.
This build has been through several different permutations over the past 5-6 months. It originally lived in some old emachines case that I had lying around (lel) then it lived on top of the motherboard box, and finally I picked up the Fractal Core 1000 from Microcenter the other day for $35 and transplanted this system to it's forever home. The build contains:
AMD A10 7850K
ASRock FM2A88M-HD+
Corsair Vengeance 8GB 2133hz
Samsung 840 Pro 256GB - OS drive
WD Blue 1TB 7200rpm drive - steam games, ROMs, etc
Acer H236HLbid IPS Monitor
Logitech K120/M100 Keyboard & Mouse
Gamestop 360 Controller (for RetroArch, Meat Boy, Skyrim, etc)
AKG K240 Studio headphones
I will post pics of the "battlestation" when I have time, but in addition to what is listed I have a KVM switch that my keyboard and mouse is plugged into. It controls this desktop as well as a notebook that is off to the side on a stand. I have this notebook also hooked up to the Acer monitor (desktop via DVI, notebook via VGA as the acer monitor has no DP sadly) and I switch between the inputs when I am working on music and videos with Ableton Live, Propellerheads Reason, Adobe Premiere, Sony Vegas, etc on my Lenovo T520 and want the extra screen real estate.
Cable management is something I want to try to tidy up, but of course the Core 1000 has it's limitations. I have that zip tie supporting the 24pin but will probably stick a self adhesive cable tie to the inside so you can't see it. Going to try to sleeve/cover those ugly front panel LED/switch wires in black of some sort also.
Future additions: I want to cut out room for another 120mm fan in the front and have two 120mm fans with fan speed reducers instead of the one single 120mm that is currently there. Hyper 212 evo for sure. AC wifi card perhaps, but that will have to wait until I can upgrade my router as well. A nicer keyboard & mouse should probably get added as well.
