I am thinking about buying one of the core duo mini's, remove the hard drive and cut a hole for a sata extension cord. From what I have seen all the of the mini styled external boxes are ide internally, so I would have to use a molex to sata power converter. I would cut a hole in the back and run the extension out. I would probaly also have to make a small hole for the extension to get out of the hard drive tray. Sata ought to be a far amount faster that firewire 400 (or usb 2) and I would not be using any bandwidth on those pipes. Other than cutting into a new mac does anyone see any problems? PS I have a dell 2405 so I do not want an iMac.
