As has already been pointed out, these are not rare - but I gotta add, they sure are well built. Mine has only had a shorted tantalum cap on the mobo and a new hard disk - but otherwise quite robust, lots of metal and gold, plastic doesn't show much age, etc. It's one of those worth more to me than I could ever sell it for. I use it just for the parallel port out to experiements (stepper motor control, etc) Kudos to Compaq for making PC's that are built to last. CHuck cswiger(a)widomaker.com
