WTB: Power Mac G4 for Applefritter

I'm looking for a G4 tower to be used to back up the Applefritter server offsite.

Here's what I need: a 400MHz or faster tower that can boot from FireWire. A Yikes or Sawtooth would work fine, but if you have something newer that would work too. I don't need RAM or hard drive, but if you have either or both, that would help. The machine needs to be fully-functional hardware wise (so no "my G4 is perfect except the IDE controllers are shot" offers, please), but I'm not overly concerned with cosmetic appearance. I'd also consider a Mac mini, G4 cube, or iMac G4; the machine just has to be able to run Tiger Server.

Here's the clincher: I can only afford to spend about $100, not including shipping. If you have an offer to make or have any questions, PM me or e-mail cwwirth@applefritter.com.

Thanks!
