I have the Asus A7M266, 1.3GHz with a Thermoengine HS and a soyo 38 cfm fan, 512mb Crucial PC2100 registered ecc memory, Herc GeForce Ultra II, Yamaha 16x writer, Pioneer 16x DVD, Sigma decoder card,Herc game theater sound, Kingston lan card, and 2 IBM 30 gig DTLA 307030 (ata100, 7200rpm) in an Enlight 7237 case with a 400w Antec p/s. I'd like to add at least 2 more HD. Right now I'm running W2k on one disk and Win 98 on the other. Do I need a controller(sp?) card or a raid card? Any input would be appreciated...Thanks😕
