MacRumors friends, I'm looking for some advice. There's an opportunity for me to get my hands on a 24" iMac at what seems a good price. Unfortunately, my knowledge and experience lies mostly with MBs and MBPs, and I'm not too familiar with the iMac line. I'll keep doing my research, but I'm hoping your advice will help me make an informed decision. iMac 24" 2.8GHz C2D 2GB RAM 320 GB HD SuperDrive model MB325LL/A (At this point I'm not certain, so assume the unit comes with the standard 256MB HD2600 pro GPU.) Seller is looking for $1000CAD, but I suspect there may be some wiggle room on that. Any thoughts on this? Anything I should be wary of? Thanks for your help!
