Dual Opterons for a ZFS server is probably overkill...there isn't anywhere near that much check-summing overhead! The second CPU expense is probably better spent on RAM or better quality drives. Be sure to use enterprise SATA for best RAID performance; besides, they aren't much more expensive. If I had your requirements on a tight budget, I'd build from either a nice used W2100z/W1100z [4-drive OEM support w/ latest BIOS] or get a new Ultra 20 [only 2-drive OEM - but space to mod]. Of course, you'll probably void your warranty modding an Ultra-20, but hey, you wouldn't have much of a warranty with a whitebox anyway. Google for the ZFS wiki...you'll know the one when you see it and they've started putting in a few performance tuning settings. Since I typically run mirrors I don't have much direct performance experience with RAIDz, but you may wish to simply make a RAIDz pool if the performance is adequate and you desire more storage space.
