Hey, I'm thinking about selling my Sawtooth G4 in order to save on space. Currently I'm using it as a file server, holding four IDE hard drives, in two RAIDs. I was thinking of getting something like this to put the drives in instead. I know that the major downside of that is that I won't be able to stream video and whatnot to all my computers, but as I'm slowly cutting back to only one main computer, that's not a major issue. Other than that, can anyone foresee and problems I would have with such an enclosure over my PM G4? And would there be advantages to going with USB 2.0 over FW400? I will be watching high-quality video which I've stored on the drives, as well as music.
