Hey guys, I am putting together a scrypt mining rig (for scrypt, and later scrypt-n, and maybe put the cards in my main computer for gaming if ASICs take over all). Also, this is my first DIY computer, and I am trying it for fun as well. I am trying to stick to a $500 budget. I have:

AMD Sempron 145
MSI 970A-G43 AM3+ motherboard
Cougar mid-tower (1 fan)
(http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3828299&CatId=1509)
2 GB leftover ram from other systems
refurb SATA 80GB (may just run it off a USB drive... your opinions?)
2x XFX Double-D R9 980

and am currently almost right at $500.

I ordered a kingwin ABT-750MM from Amazon today for $35 (ABT-450MM got a decent review from hardwaresecrets), but am wondering if I shoudn't get the Corsair CX750 for $60 from newegg, or maybe get two CX430s for $40 (one to run one video card, other for everything else - but heard that there may be problems with this, even with the add2psu adapter).

You guys see any big problems with my build, and also, what is your recommendation on the power supply issue?

Thanks!!!
