The reason I run slaves at 30 fps is because I read that it has a significant effect on the slaves follow performance. Having said that, my slaves still lose follow when changing zones, but that's the only time I see it.

WRT cooling, I'm running the Noctua NH-D14 and it is damn quiet and keeps the 4930 cool, but it also requires low profile RAM and covers up half my motherboard. And is ugly. I don't have a window in my case, so I'm good with ugly, but if you care about the aesthetics you wouldn't like it.

SSD? I run WoW off a single SSD (Samsung 840 Pro.) I have the OS on a separate SSD. I don't really have any trouble with the single SSD, but I'm considering adding another (128 GB) SSD to set up in RAID-0 simply because the 128 GB SSDs are cheap and umm... I dunno, everyone is doing it.

We haven't heard MiRai's review of the RAIDR yet, but I've read a lot of reviews that say that standalone SSDs are faster and more reliable.

I've got a Corsair PSU like MiRai's, but don't let the "CorsairLINK2" press suck you in. It was a major feature that sold me on the Corsair PSU but now that I've actually looked at it I find it not nearly as useful as OpenHardwareMonitor. Still, the Corsair PSU is quiet, good looking and comes with a ton of cool cables and other junk.
