Bought this from Stallion tech. Added SSD, moved HDD from old computer and replaced Quadro 600 to Quadro k5200 ( 325 from ebay) . Under 1000 this is a beast, Geekbench 25800, Cinebench CPU 2080, GPU 119FPS. In real life very snappy and fast in everything I do. Beautiful chassis ( was designed by BMW) and inside very well organized ( close to macpro 2012!) . Some people are concerned about Ram 1060 GHZ but did a lot of research  AND slower RAM has very little effect in real like, may be decrease FPS by 5%-10 % but hardly noticeable if you are not playing games in very high settings. In my opinion its a steal.
