Intel DP35DPM Socket 775 Barebone Kit / Intel Q6600 2.40GHz OEM / 200GB HDD OEM / 1GB DDR2 PC5400 / ATX Mid-Tower Case with a 500 Watt Power Supply
The PSU is not exactly top of the line, being an Ultra one, but it's not a crappy no-name brand either. I don't know how much of a difference the RAM's speed will make but as far as the brand goes, I don't see any bad reviews about Ultra RAM online and even if it does go bad, it comes under warranty from Ultra. The HDD is a Maxtor DiamondMax 7200RPM one, so it's of good quality as well. The mobo has a P35 chipset so it has support for Penryn and DDR3 as well. A steal at that price IMO.
