A barebones recommendation

What would be the best barebones kit for the money.

I am trying to build a really cheap pc for my familly. The most they would be using it for is to play sims 2...

The Sims2 is really bloated and resource hungry, barebones isn't gonna cut it.

I lol whenever people say they need "barebones" or whatever and then they explain that they only need it for playing games. Newsflash: games are pretty much the only thing that actually require anything more powerful than a 486.
