Sadly, if you buy a setup like that even on the Dell outlet it'll run you into the $5k range.
I've got six T5500's and a few T7500's (just bigger fit up to 8 HDD's) and love them. They are rock-solid and don't break, ever.
I searched Fleabay for "Dell T5500 X5650" and got this:
(Search Results) http://www.ebay.com/sch/i.html?_trk...5650&_nkw=Dell+T5500+X5650&_sacat=0&_from=R40
or this: http://www.ebay.com/itm/Dell-Precis...1391207002?pt=Desktop_PCs&hash=item338bf1ba5a for $1,000 plus shipping. All you'd have to do is put in the hard drive configuration you want. Depending on the Service Tag it may have a warranty.
If you buy in-warranty it'll at least double or even triple the price. At that rate it's just as easy to have a spare box standing by "just incase".
Good luck!
I'm one of those guys who spent 1700 on an i7 with like 25gigs of ram. And now the computer is going kaput.
I don't have the time build or upgrade a PC. But I also don't need to go crazy. I use Bloomberg, several instances of excel and one instance of SQL Server 2010. What would be a good reliable PC for that? I used to be more involved in the PC specs, but I've lost touch over the years.
