I have come across an early 2008 iMac for sale by a neighbour for a decent price ($700ish)... Good deal? Any issues with these? I know sometimes the first-gen of anything can have some problems. It won't be used for anything crazy, just typical office / internet, so graphics performance isn't a huge issue and the C2D should be fine. Just looking for some input, as this will be my first iMac / desktop mac.
