I got a barebones system, and I tell ya: I'm loving this computer.  It's speedy enough for a media center system.  The biggest gotcha is MEMORY.  Not just any memory will work in this system.  I got "Unsupported memory density" errors in two sticks I tried.  The 3rd stick finally worked.  Search for CT2K51264BF186DJ in order to find 8GB of memory that works with this machine!  I only wish that this machine ran Windows 7.....  But W10 is okay, too....Update: Replaced this computer under warranty and the replacement is acting up.  Downgrading the unit to 1 star, as I shouldn't have to deal with hardware that acts up constantly....
