Computer Work and Home Networking

My desktop PC died a horrible power-supply death a few months ago.  A good buddy hooked me up with a spare PC he had laying around, sans a hard drive.  Today after my mentor meeting, I'll be getting started trying to get the old HD installed in the new PC.  After that, I'll be setting up a network for my home, so any device can access storage on the server.  I've been wanting to have a "home network" for years, but never really had the gumption to make it happen.  Let's see if I succeed on the first shot :)
