The NUCs come in two form factors, with the smaller one supporting M.2 SSDs and the larger one both an M.2 and 2.5-inch SATA SSD. There are Core i3-8109U and Core i5-8259U models at $299 and $399 respectively, but the one you really want is the $499 quad Core-i7 8559U model. All pack four USB 3.0, one USB Type-C (with DisplayPort 1.2) port,HDMI 2.0a and a pair of SATA 6.0 Gbps ports.
Keep in mind that the prices shown don’t include RAM, storage or an operating system. If you get a decent 512GB M.2 SSD, 16GB of RAM and Windows 10 Home, you’ll be pushing $1,000 on the high-end Core i7 model. Still, that’s not too bad for a relatively powerful PC that fits in the palm of your hand.
