So I have a couple of old desktops laying around, and it dawned on me to just make my own servers. The best one I have has about 256mb, and anywhere up to a 80gb hard drive. I would definitely go with a linux distribution for my OS of choice, although Im a little confused as to which to use, as never having to use a server version instead of desktop/end user. Obviously I need something that can run minimally, and I dont think Ubuntu server could do that very well. Ive taken a look at CentOS, but what would you recommend? Thanks.
