Hello everyone, I've been using Linux for the past ~6months and really enjoy it. I've read a few books so I have a good grasp of linux fundamentals but want to up my skill and have always liked projects as a way to learn. Anyway I would like to build a Centos mail server, file server, try some encyrption, ssh, just learn and build something.
Anyway, what would you guys reccommend as solid hardware for a home server? I'm looking for something cheap so an old desktop tower would work but low power consumption and compact size would be nice. I couldn't find anything worthwhile on craigslist but there is tons of stuff on ebay and I don't even know where to start.
Can you please recommend some hardware, maybe even specific models that you personally have used and liked, I really don't want to spend more than $100.
Thanks in advance.
