Please help me identify which model quicksilver this is from these pictures. He told me that it has a 40 gig hard drive and the back of the machine says model #8493. Near as I can figure out from google that just designates it as a quicksilver but nothing else. I think I have a good deal here, I'm about to buy a quicksilver from the guy for $75. Even for the low end quicksilver $75 is a good deal, yes? But it's a bit of a trip for me to pic this up so I want to see if it's worth my time. Is there any way to tell from these pix which model it is? Can we see if there are dual CPUs? Any other identifying items here?
