Both of these servers have been in use for less than 2 years and are in great shape.
The dual AMD is built around a Tyan 2466 motherboard and can be upgraded to a dual 2800MP, up to 4GB of ram. It would make a great box to host a bunch of websites on.
I am asking $450 for the dual AMD and $250 for the celeron box. For shipping purposes, the boxes weigh ~38 pounds (dual) and ~28 pounds (celeron). They will be shipping from 55428. I will accept payment via Paypal or money order/check.
