Hmm, I have a micro atx am2 mobo with athlon x2 6000 3ghz, and 4x1gb ram in it if you're interested. It would help fund an fx6300 secondary rig I've long been waiting to build. All I need for the fx6300 rig is the cpu,motherboard, and power supply.
Not sure if that would work with your front I/O though, those tend to be finicky on prebuilts. It does have IDE though, it's how the current DVD drive is hooked up, and appears to have a spare IDE slot too.
