Add in a 17" refurb lcd for 99 or 19" for 109 and I that box is much faster than your ebay deal
That also includes a 1 yr warranty and has a dual core cpu, 4 times the memory and 8 times the hard drive space and will last you a lot longer.
My brother in law got one of theirs last year like this and has been a great little web/email machine that will last him a while
