I have a need to have a machine run some scripts every evening (backup jobs of websites). Right now all I have are MBP's and I kick off the script manually when I get home and have one of the MBP's on. I'd like to have a machine that is a small footprint that would essentially be an always-on device...that I'd simply remote into from one of the MBP's when needed. So I was thinking of a Mac Mini for this (or some other really cheap linux box but finding a small, cheap, low power linux box is proving difficult for some reason. That said to do what I'm looking to do (Which right now is an automator action that calls Transmit FTP and some apple script), could I get away with one of the G4 mini's...or one of the very early Intel Mini's? I'd need to at least run OSX 10.6.8. I probably don't want to spend more then ~$200. Also this would be in my bedroom...is there any noise to them? I'd probably schedule the script to run at like 3am or something.
