Legit Reviews posted a review on the Intel NUC DC3217BY Barebones Kit
During the Intel Developer Forum 2012 I was able to sit down with some Intel engineers that were in charge of developing the Intel Next Unit of Computing or NUC for short. This was back in September and they showed me the NUC in all its little glory. I say little as this PC measures just 4.59"x4.41"x1.55" and it has a weight of just 18 ounces! Think of the Intel NUC as a desktop version of an Intel Ultrabook if you want to keep things simple.Intel NUC DC3217BY Review w/ Windows 8
As you can see from the table above, Intel is making you choose between having Gigabit LAN and Thunderbolt. You can't have both in this first generation device. Both versions come with three external High-Speed USB 2.0 ports. Why didn't Intel include SuperSpeed USB 3.0 support? I have no clue as the Intel QS77 Express chipset has native support for up to four of them.
