Monster-Hardware reviews an incredibly low priced case that would be perfect for building a cheap PC.  If you have a family member that needs a PC built, consider this CableMart case for a starting point.
“”As mentioned, the power supply is rated at 500 watts. Understandably, at this price point, the power supply is not a major brand! However, the voltage levels remained steady while I performed initial testing. If I had to give a negative about the supply, it is this — there were only four molex connectors. This really isn’t a negative for the average user — but then again, I’m not an average user, generally having four hard drives in use at any given time.””
