Hm.. if you want a machine truly built well, and out of quality parts, I would recommend http://monarchcomputer.com. Their customer service is very friendly - you'll speak to a person who knows their stuff within seconds if you call. They offer only top-notch parts and components, they perform a proper burn-in and test for you, and their wiring jobs are extremely tidy.Unless, of course, you get some enjoyment out of slapping the parts together yourself.. which can be fun the first few times. Having built, troubleshooted, upgraded or repaired dozens upon dozens of boxes myself over the past 14 years.. it gets old, heh.
I hear that all of tigerdirects items are refurbished and or defective.
