I built this as the main rig for movies, music, surfing, and "productivity."
It has five 5TB drives in raid 5, five 3TB drives in raid 5, two 2TB drives in raid 0, and one ssd for the OS.
The 95 watt FX-8320e stays very cool. I bumped the voltage on it by .15 volts to make it run 4.0GHz all the time. It works great for packing/unpacking files and for HD movie compression.
32GB of ram seems like a lot, but I routinely have 16GBs worth of Chrome tabs open, so I added the extra memory.
I picked up the XFX R9 270x a while back and it performs flawlessly (much better than the old HD4350) for madVR rendering and light gaming. The only complaint (sort of) is that the fans are always on. They are barely audible, but I'd prefer they be off in the htpc (as all the r9 285 and 300 series cards now have the "0 decibel" option). Yeah, I know...a 750ti would have been plenty, but F nVidia.
Anyway, it does everything it's supposed to do and does it 24/7 without making too much noise or heat. The software raid 5 has slow-as-molasses write speeds, but it's free with Windows, so I can't really complain too much. Aside from that and the lack of a 0db fan option on the video card, I'm very pleased with the machine.
