This is a new IBM/Lenovo Thinkpad Systemboard. The FRU number is 39T5501. This motherboard is compatible with the Thinkpad R51 laptop. This item is new and has never been used. It was originally made for use for an OEM as a part of a system. Even though it may have the same part number as a standard part this item may be configured specifically for the OEM that originally ordered it. We have re-packaged them for individual sale. It is being sold as pictured and does not come with any additional parts or accessories.
