Summary: Purchased this used, which I am not in the habit of doing. I do own 2 other of the same and know exactly their actions. This one is perfect also. Installed on a Asus P5G41C M LX motherboard, Zigmatek cooler, 2 Crucial 4GB sticks of memory, Samsung 1TB drive and Antec 550W power supply. A little more life for the first system I built a few years back. A great Internet scooter. Arrived on time, packed very carefully and showed little use.
