With this build I'm aiming to prioritize noise reduction without sacrificing performance in games and graphics-related applications.
Some basic numbers:
CPU fans idle at 265 rpm and 38 C.
GPU fans idle at 500 rpm and 40 C (flashed BIOS).
Case fans switch on at 50 C.
CPU/GPU hit 50-55 C under load.
Additional details: Western Digital Reds were the quietest 2TB+ hard drives I could find but they're just barely audible when there is no other sound in the room. Otherwise this build would be completely silent when idling/browsing. Still waiting on the LG monitor from Massdrop, but otherwise everything's up and running. Plays Elite: Dangerous on Oculus DK2 like a champ.
EDIT 1: I've received a boatload of awesome tips and suggestions from the wonderful community here. I'll post an update some time in the next few weeks with all of the changes as well as pictures of the completed setup and workspace (including all of the peripherals). Thanks everyone!
EDIT 2: I switched out the Rosewill RNX-N250PCe wireless adapter for a ASUS PCE-AC68 dual band 802.11ac adapter. The Rosewill adapter was perfectly fine until we upgraded our router/modem/internet package today and moved the location of the router. After doing some reading and getting up to speed on what all those networking standards mean, I decided to go for a nicer wireless adapter which will be compatible with Time Warner's 300 Mbps service that's coming to my area next year.
