I currently use a MacBook Pro as my main machine. This is currently the only computer I have. I like to download a lot of torrents, and it annoys me having to do this on my main machine for numerous reasons. I have thought about the possibility of buying a desktop machine for downloading torrents (and perhaps some word processing). I'm looking for something that is: Cheap, Low power usage, Relatively compact, Quiet, Wireless (to connect to Airport Express). I have thought about an Eee Box and Mac Mini, but both would be too expensive. I also thought about a G3 iMac, but the ones I see on eBay always have tiny harddrives, however I'm not too sure about the power usage. I've started thinking that the best thing to do would be to build something with a Celeron or Via processor, and stick a 1TB harddrive in it. But I don't know if this would be sensible. Does anyone have any ideas? Power usage is important as it'll probably be rarely switched off, and my parents moan about such things.
