Order this and it came very poorly packed for the size and weight of a work station.  Did not have the correct graphic cards.  Had one off brand card in the machine.  Contacted the seller and claims cards did not pass inspection.  Sent what they claim are an up grade to the ones supposed to be in machine. Had to contact them for the missing keyboard mouse and windows disk.  They did give me $50 back for my problem but still feel lime it was not worth all the back and forth to get what I thought I was buying.  It was dirty inside and never cleaned out.  A can of air is cheap but was never done.  Still have no key fir the windows 10 but have the disk.  Just poor experience all around.  Read reviews and thought it was worth a gamble but I lost.  It has cost me lots of time and for the price I thought it would have been presented better.  I will make it right on my end having some knowlege of what needs done but average guy will be returning this for sure.  Buyer beware.
