Thanks for your response. I didn't even get as far as scsi. I figured I'd get a low budget system to run w2k server to practice for the exam and I'll get a monster system later to network all my systems together. I couldn't find the mobo I was going to purchase on the HCL for w2k server. I have an opportunity to purchase a system this weekend for about $450-$500 (1.5 xp amd,512mem, 40 gig hd mobo ecs k7s5a)Not On HCL!! w2k server warns about purchase not on the list. What do you think?
