The ASUS A8V-VM SE motherboard with an Athlon 64 3400+ CPU is a reliable and high-performance option for building a compact computer system. With a MicroATX form factor and Socket 939 compatibility, it'll fit in smaller cases, but has enough expandabiilty to support dual core CPUs as well. SATA and IDE onboard, built in VGA, Audio and Network, with 4 USB2 ports on the back and headers for four more on the front of whatever case you put it into. Supports PCIe with 1 x16 and 1 x1 slot in addition to PCI slots.
Fully tested, refurbished where necessary adn thoroughly cleaned, this board is 100% in working order, and comes with the original box, manual, IO Shield and case badge. I'm also including the driver CD for completeness, but it was shattered before it came to me and I only noticed that fact when I went to put up this listing.
