If you're looking to sell your iMac, willing to buy based on Mac2Sell prices provide you have box, keyboard, mouse, and original install DVDs, and it good cosmetic condition. Under $1,000. Doesn't matter white or aluminium iMac, must be Intel based. Based on me wanting to spend closer to the $500-600 range, I'm probably going to opt for the white models. Size doesn't matter, it's all an upgrade to my failing eMac (logic board going bad).
