Intel has cranked up its NUC (Next Unit of Computing) mini-computer to near gaming levels of power with the release of its 4th-gen Core-i5 D54250WYK kit. The new model comes with the latest HD Graphics 5000, for one, and also uses Intel's Turbo Boost Technology 2.0 to ratchet the CPU clock past stock levels when the need arises. It's got the chip giant's Quick Sync video to speed up encoding, a DisplayPort 1.2 jack with 4K capability, four USB 3.0 ports, an infrared sensor, stereo/mic jacks and a gigabit Ethernet controller. There's no pricing or date yet, but bear in mind that you'll need to add RAM (up to 16GB), an mSATA drive and some kind of monitor to make it fly -- though dwarfing it with a 4K display (like this one) might be overkill.
