I've built 4 other PCs in the past year, but they've either been super-budget boxes for family or purpose-driven PCs (unRaid NAS & HTPC). This is my first shot at a performance/gaming build for myself.
The case was amazingly easy to work with, so the whole process went super smooth. The only caveat was the 212 Evo cooler. It was touchy, but seems in the end worked out. Next time it will be easier.
I've left the stock sound-dampening in place, and it is ultra quiet to my ears. The ceiling fan needs to be fixed next, 'cause that's all I can hear now! I used the two new BladeMaster fans in push/pull on the cooler, and my temps seem pretty good thus far. When gaming, the fans pick up to ~50% using the Asus FanExpert "Performance" preset, and temps only increase ~ 10-15 above idle. No need to overclock ATM, but it seems I have plenty of thermal and dB headroom.
So far, I've played Bioshock Infinite on Ultra and Crysis 3 on Very High with SMAAx4 and am loving it! I'm downloading GPUTemp & 3dMark right now, and will post those results soon.
