8+2 VRM. Perfect, if you never plan to SLI. On that note, its pretty difficult to find a budget board for AMD that supports SLI and with two x16 PCIe slots also. Mine does but its $140... kind of but not truly a "budget" board (well, compared to $200-300 options it is, but anyway).
Specifications on that board state only Crossfire (AMD) and the second PCIe would run only at x4 too, so you'd never be able to SLI on it, and if you went AMD GPU it wouldn't really be worth Crossfire anyway (performance boost would be severely undermined on the x4 side). Just a head's up.
Also, for the FX CPU, you may need to update the BIOS before it will work. Plan accordingly.
As for a case, I would recommend you chose it based on cooling foremost in mind. Its more cost effective to get one that already has all necessary fans included. Bonus if you find a case that has ALL fans installed, not just an intake and an exhaust, and doesn't run over $150. Fans cost a hell of a lot IMO, enough to defeat the attempt of going for a rock-bottom budget case... you'll spend $50-100 on decent fans, so you might as well have just dropped $100-150 on a case including them in the first place. And again, also ensure the case you choose can accommodate a decent aftermarket HSF (a Hyper 212 Plus at the very least would be my recommendation there. But really, you'd want something just a bit better for either an 8320 or 8350). You will definitely need a good, beefy one for that chip. Just trust me on that. They really do run hot. If you chose a case around 9-10" wide, you should be golden for just about any aftermarket cooling.
