I'll add some pics later. All parts are from Microcenter. Everything works. Posted on first power-on.
This build is still a work in progress as I plan to replace the stock cooler and add a couple fans. I chose all parts based on price/performance and/or known reliability. Coincidentally, everything is black, which is cool, but makes the R2's tinted window useless so I'll add some leds too. I'm also waiting on a Dell U2412M, so I'll add input on that later. Right now it's just plugged into an HDTV.
I'm dual booting Windows 8.1 and Linux Mint 16. Mint supports the Realtek ethernet out of the box, but you might have to find the driver if using another distro. Also, you'll need to enable IOMMU for GNU/Linux. In any case, the motherboard is a good deal if you're not planning on multi-gpu. I noticed the UD3 had a lot of negative reviews, but the UD3P, although less popular than the the AM3+ boards, has almost unanimously good reviews. So far I've only had time to play the first Crysis, but it played smoothly on very high settings and 3dmark/heaven benchmark scores are up to snuff with everyone else sporting the 270x (a little better in some cases with the Asus card overclocked ootb), so the card hasn't been limited by the motherboard or the cpu thus far.
The case is really newb-friendly as I ran into zero problems and organized the cables with little effort. It's very sturdy and keeps things nice and cool. Between the R2's fan controller/140 mm and the Corsair PSU's quiet mode, I have no noise complaints.
