MegaMacs offers the refurbished Apple iMac 20" Intel Core 2 Duo 2.66GHz All-in-One Desktop, model no. MB324LL/A, for $299.99 plus about $25 for shipping. That's $95 under our winter mention, which only had 2GB of RAM, and the lowest total price we've seen. (It's $128 under the lowest total price we could find for a similar iMac today.) Features include an Intel Core 2 Duo E8335 2.66GHz dual-core processor, 20" 1680x1050 LCD, 4GB RAM, 320GB hard drive, DVD burner, NVIDIA GeForce 9400M 256MB graphics card, Bluetooth 2.0+EDR, AirPort Extreme (802.11n wireless), iSight webcam, and Mac OS X 10.6 Mountain Lion. Deal ends September 30.
A 30-day MegaMacs warranty applies.
