I have been a long time user of ASUS products. It is time to rid myself of my collection of older equipment. I think all are working. I have: 1) 1 P3B-F that was in service until yesterday and has refused to die. 2) 2 P4C800-E which have not had the USB ports latch up. 3) 3 P5W DH Deluxe. For all, I have CPUs and ECC memory. If any one is interested in this equipment and is willing to pay shipping, then can discuss further what parts I have. I have original boxes, manuals, cables and I/O shields for these motherboards. None were overclocked and all were kept cool. I am in the Phoenix, AZ area. Regards,
