A:Answer Hi. The included motherboard is a stripped down ASUS F2A55-M. They have removed the legacy PCI slot and 2 SATA ports, so it only has 4 SATA ports and PCI-E x16, x4, and x1 slots. Because of these changes, the BIOS/firmware is different that the standalone board.
The PC certainly has a lot of upgrade potential.
Hope that helps.
