We have already seen a mini PC by VIA. Recently, Intel jumped the gun and introduced its own mini PC — the Intel NUC (Next Unit of Computing). Priced at $400, the Intel NUC support up to Intel Core i5 Ivy Bridge processor and feature 4GB DDR3 memory, 40GB mSATA SSD, WiFi, Bluetooth, mini DisplayPort, and HDMI.
Though it is expensive, Intel NUC is a good bet for use in enterprise segment.
Intel NUC will be available in Q3 2012.
