ok, i am looking to buy a computer from HP. I custimized it and wanted to know what the motherboard is. I did some searching, i foundthis page. It says that the motherboard is ASUS: K8N8V-LA PES HP: Diablo-GL6E. What does this mean. It looks like their are 2 motherboards. when i get this computer, will i still be able to upgrade all of the hardware when needed?
