Hi guys, After umming, ahing, I've finally bitten and have ordered a dual 2.5 off the apple re-furb store for £1400. Can't wait to get my machine :-D I have a question about upgrading the Ram however. It comes with 512 MB. I hear you have to install ram in the powermacs in pairs? is that true? Would crucial ram be ok? Do I have to worry about CAS latencys for performance like on a wintel PC? Any advice you can give me on what to get before my new baby arrivies will be of great help Also, as it's a re-furb, it has no airport or bluetooth. I can buy a cheap airport card if required no problem, but is there any way I can add bluetooth to this monster?
