Built my first rig a year ago, finally getting around to writing a tad about it.
Should not have gone with a triple slot card - fits with too little room to spare in the bottom PCIe slot when using this case.
Highly recommend connecting all necessary fan headers before installing the CPU cooler if using one similar in size to the D14. It was a pain connecting the fan header under the cooler afterwards.
D14 overhangs two of the RAM slots, so installing two more sticks while keeping the cooler on was a very tight squeeze (the remaining two empty slots were the ones under the cooler).
Unigine valley bench in pictures was complete 8/31/14 using 14.4 (I think) drivers.
Firestrike score of 9877 on 10/21/14 (http://www.3dmark.com/fs/3031931)
The D14 sags a bit on its own, but the side fans prop it up!
Asus mobo Bios/software is fantastic.
Excellent for small rooms in cool climates.
