I bought this little micros to run a security onion instance in my home.  Time went by and I did not get a chance to fire it up but I thought I would over the Christmas holidays.  Hooked up keyboard, mouse and monitor to be met with bios beeps.  3 short and 3 long.  This error means. 3.3 (blink/beep).  Hardware: The embedded controller times out waiting for BIOS to return from graphics initialization or if a graphics output device failed to initialize.Contact support for repair due to graphics or video failure.I opened the case to clear the CMOS and notice that one of the screws and guides to hold the hard drive in was missing.  Removed the heat sync bracket.  Cleared CMOS.  So I get to buy a new motherboard for the thing.  Lesson learned.  Plug stuff in that you buy refurbished right away so you can send it back if it fails you.Not impressed.
