I remember owning a E8400 on my Gigabyte DS3L and it had pretty good speeds so I believe these speeds will satisfy my needs. The main selling points for me are E8400 processor and that this setup has E-Sata so I can easily sync/transfer data between computers.
Is this setup compatible? Can I get anything better for similar price?

I would sooner buy a used pacemaker than computer equipment, especially on Ebay or Craigslist. Unless you know the seller (who must be local) and they have agreed to take back the item if it doesn't work to your satisfaction.....forget it.
A lot of times businesses replace all their hardware when the warranties are up, so perfectly fine hardware gets sold off for something new that is covered by the manufacturer. A seller with many of the same computer is probably a good example of this and I would imagine for a cheap spare computer it would be okay.
