Intel certainly knows how to present new products. Minor improvements are often dressed up as revolutionary updates, so it's no surprise that when the company introduced a mini PC, it wasn't presented as a normal mini, but the 'Next Unit of Computing.' We did like the first edition of the NUC, apart from the fact that it lacked USB 3.0. That's something the more compact Gigabyte Brix does feature. The new DC53427HYE takes care of that part, and then some. With the built-in vPro feature the NUC is now compatible with business applications.
The dimensions have remained exactly the same at 112 x 117 x 42mm. So it's a compact PC, using the same type of hardware found in Ultrabooks. That means a very small mSATA SSD for storage, and two SO-DIMM memory slots, along with space for a wireless card. There are an increasing number of products available that can be combined with the NUC, such as the MD BRPCV01 from IIyama or the special passive case from Silverstone, even if the latter doesn't appear to be compatible with the newer NUC.
The Intel NUC comes barebone. And, as is the case with Intel's CPUs and SSDs, you can buy it as a boxed product which includes components for mounting it on a monitor or TV with VESA, along with a power supply. You don't get the cable for the power supply, though. You can decide how much RAM you want, how big the SSD should be and whether or not to install a Wi-Fi card. Of course there's no operating system included, so you need to consider that as well when you calculate the total price. You can also just buy the motherboard of the NUC, called the D53427RKE.
