RAID 0+! is by far the more inefficient resource (amt of HD) type RAID out there... I also didn't suggest 16MB cache as those are only needed for larger drives. Yuh doh see a 80GB with 16MB cache... at least not normally. As for raptors... they ARE overpriced... however perhaps 2 74GB raptors in RAID0 + 2x 400GB drives for storage would be nice :p I would suggest an 8600GT as the preferrable BASE card (yes they are NOW available) and their performance is JUST above that of a X1900XT (256MB) card. I know cause I JES looked at the benchmarks for that card against my own. 4GB of RAM is fine esp if yuh planning to run Vista and well thats about it really... get a GOOD FULL SIZE ATX CASE!
