So this guy on craigslist is selling a 24" iMac that has apparently just been sitting around for a year without a hard drive or memory, but that's all that's missing. I'm taking this to mean that if I stick in a hard drive and some memory, it would boot up just fine? Or would I have to maybe replace the little battery on the motherboard and so there's no real way I can test if the computer is alright? He's selling it for dirt cheap, and a hard drive + memory would not be expensive, either. Cheers!
