I bought 6 of these late last year as our company is expanding, but didn't install them until we had received our work stations in March of this year..  So far, 3 of them have failed after several months of use, a message appears.. Hard failure, not all at the same time, but within month of each other..  Warrantee was only 90 days..  So, you can buy one of these and take a chance, Now I'm in the process of replacing all these pc's with brand new units!
