I personally wouldn't even go for a used server. They're generally loud, and even when they aren't they use much more electricity than what you would get from a consumer platform. There's really no benefit unless you have room in your house to make a real server room with racks and the electrical capacity to go along with it.

It also uses a server socket, so the only motherboards you're going to be able to find are server motherboards. Those are going to be expensive and/or have other quirks, such as requiring a vendor specific heatsink, or a vendor-specific power supply, or take 5 minutes to start up, etc.
