First, out of the box it is an okay machine.  But try something fairly simple, like add an SSD with Windows 7 for dual boot nearly impossible.  Bios boot controlled by Windows Boot Manager!  Customer support was pretty pointless, as they could not tell me any documentation on how to set up a dual boot, even told me it could damage my system!  Customer support cannot research my questions and email the answers to me either.  So disappointed.  I've been building PCs for 30 years and never encountered such closed practices.  Power supply not standard either.  Buyer beware!
