In lieu of building a home server, I highly recommend the Synology line of NAS machines. They've got everything you could possibly want out of a home server, with a much faster configuration. Automatic backups, a built in Torrent server, Plex media server, and remote file access all in one container.
Seriously a great product and value if you're looking for a home server.
You're not comment crapping at all, you're offering a great alternative to those who are time rich / cash poor, or who like configuring and want to learn about building servers. For anyone who's cash rich and time poor, the NAS products from Synology are great.
