I Have a custom built computer that I built 4 years ago or so. The Hard disk died and i am not going to replace it. It comes with every thing else thoughit ha 4 gb or RAM an ASUS mother board. It has an AMD 3 core processor. It was used as a Home theater. The power supply was replaced about a year ago. This is a great computer for parts or replace the hard disk and it will work for a long time.
