I bought a M950 motherboard, 512 MB RAM PC 2100, and a 40 GB hard drive with a whole bunch of programs on it and Windows corporate.. It was only $115.00 and nothing is wrong with it. Kinda a steal I think. Anyway.. there is no processing chip or power supply. I have a power supply that is 250 Watt and want to make sure that would be enough to support my computer till I get better one. I don't have chip though.
