I just got done building my new computer. I'm going to try and sell my old computer to a friend and have no idea what it's worth. It's an old Dell Dimension 8100, Intel 850 Motherboard, Intel Pentium 4 2.5 with a 400 FSB (Using a Powerleap Adaptor, it was a socket 423 and is now a socket 478), 4 128 Meg sticks of PC800 RDRam, Visiontek GeForce 4 Ti4600, Turtle beach santa cruz sound card, 56K Modem US Robotics on board 10/100. I'm going to sell just the tower with no speakers or monitor. I do have a keyboard and mouse but those aren't a big deal. I was thinking of asking 400-500 Dollars. Am I too high?
