Other than wondering how cheap you got the 590, having oodles of RAM, and the quite adventurous RAID setup, it looks pretty good.

I would recommend a 640GB RAID 0+1 though, with 4 HDDs in RAID, you're looking at ~10% of data corruption.

620 isn't necessarily cheap though, just a good deal, as dual 6950s pretty much match these for less than $500. But there is the higher resale value.

i guess the 10% of data corruption well be a problem
