I have an early 2008 24" iMac (2.8Ghz Core2Duo, 4Gb RAM) and has served me well. I'm not quite ready to replace it yet. It's still fast enough for what I do (and it's by no means a slow computer). I would, however, like to replace the small 320Gb HD with a 1Tb one. That way, I'd have enough space to make two 500Gb partitions, one for SL, one for bootcamp Win7. All the games I have (Wow, WC3 and Steam games) work with Windows as well and that would, in a sense, make my computer faster for games. For a relatively small cost, I could have (kind of) have a new machine. But, is it safe/difficult to do ? I've seen some guides and it involves removing screws and wiring. I'm afraid I'll ruin my iMac. Can anyone provide me with some useful tips ?
