Unit was ordered new with a business purpose in mind but never materialized.  Obviously, you can't return a custom built server so I've decided to sell it.  Has windows server 2008 foundation with AD.  Has 8 additional HD bays for expandability and the drives are hot swapable.  Has primary and redundant power supply.  Please look at build specs in the photos.  Labor and tech support warranty is lifetime.  Unit has less than 300 hours runtime on it.  Clean unit everything looks brand new under the hood.  Paid just south of $4200.00 new.
