I need to get a new machine, as my 3 year old 17" iMac's logic board is fried. (unfortunately, revB's are exempt from the extended logic board warranty ) I can't spend a ton right now, but the 24" 2.16 Core 2 Duo refurb is attractive to me for a couple of reasons, mainly the matte screen and the price is nice for that kind of real estate. I've also heard some conflicting reports about the aluminum cases. Does anyone have any experience with this machine? Good, bad or otherwise?
