Ok...as in the topic...I plan to use 2k Pro or Server, this is for some work in my comp sci. classes and to host a small website. Which OS and what processors/MB should I use. I already have a single 18.2 GB WD Enterprise and a P3-450, should I use the 450 or go something faster...and I think the HD should be enough..and I have a controller for it. TIA
