Like the title states. It's an oem copy. I bought it and never used it, but it is open. I would like to either trade it for a 32 bit version of Windows XP PRO, or sell it outright. Will include a small piece of hardware to comply with Microsofts rules etc... Looking in the $75 range. Or a heads up trade for 32 bit XP Pro Also have a Razer Death Adder. Gently used looking for $25 + shipping. Any questions just ask!
