Yep, many companies don't upgrade these machines and actually dump them at the end of the warranty. Hacker news actually turned me onto going to ebay to buy used workstations as a pretty good source for inexpensive computers that have Xeons. HP or Dell give you a 3 year warranty, you don't upgrade or change parts because that fucks with warranties, then you dump them onto a reseller. Or, frequently, you actually rented it from HP or Dell for those 3 years, and they are the ones dumping computers onto resellers.
