Both of these were purchased refurbished.
EX470 full disclosure: I ran linux on this so I think the built in flash memory was probably formatted. Not sure if you could get Windows installed on it again. Also, as detailed in my other posts I never could get two of the hard drive slots to work, but I'm not sure if it's the slot or the drives I was using (Western Digital Caviar Greens). Comes with just the tower.
EX485: in awesome condition, only ever had Windows on it. Comes with original manual, cables, CD's, etc.
Pricing: I will accept the best offer plus whatever it costs to ship to you with the method of your choice. I am located in NC. Ebay profile if interested:
