I'm looking to hang my G5 from under my computer table to give my desk an open feel. I dont really want to leave it on the floor directly because I think it may take a little abuse, and is closer to dust/dirt particles as I dont vaacum too often. I'd prefer it just held it from the two "handles" on the top of the case, but I dunno if that's considered unsafe. Otherwise, I'd settle for a full bracket if I had to.
I could certainly rig one up on my own with a little research and a trip to home depot, but I'd love to find something that is well built to support the weight of the PowerMac.
