These things are GREAT!  I purchased this one for a friend who just opened a new business and needed a point-of-sale system.  I knew she'd be short on counter space after having the cash-drawer, etc and a decent sized monitor, so I suggested she let me build her a NUC.  She couldn't believe how small it is, how fast it is.  A few days after I installed everything, her husband was at her store and he asked where the computer was; she pointed to it and he still still couldn't find it.  If you are building a new system, remember if you find a monitor which has VESA mounts and a stand - which can both be used at the same time; then you can mount the NUC to the back of the monitor and get away with very short video cable and less clutter.  I will continue suggesting these for anyone needing a Windows based PC
