My purchase from them did not go well.  From the moment the machine arrived it was giving me little problems here and there.  Like missing caddies for disk drives and faulty ram modules.  Just one month before the 12 month warranty was about to expire a PCI-E slot went bad.  I had to remove the card that was in it before the machine could boot up.  They wanted me to ship back the entire server with my private files and software rather than send me a replacement motherboard.
