Gigabyte BRIX "NUC" type Micro PC.
These are attractive machines that have been tested to power on and are perfect for lots of uses, but there are a few caveats...
1). No power supply included - the good news is just about any 12V to 19V power supply that fits will work.
2). No SATA HDD cables included - This particular model /may/ not have shipped with these in the first place as a 2.5" drive would be an extremely tight fit in this case, but they do have a connector where one could plug in. It's more likely, however, that this model was intended to use only the provided the mSATA SSD slot.
3). Some of these units have BIOS passwords. There /IS/ a reset procedure, but we're honestly not sure what it is for this model. (It may be as simple as removing the CMOS battery.) In any event, even the units with the password are not fully "locked out" - if you insert a drive with an operating system it will boot as normal, you just can't access the BIOS.
4). Condition varies from unit to unit, but generally these are in good physical condition but may have some marks/scuffs on the black lid and some sticker residue.
