Perhaps it's because I have not upgraded my motherboards in 6 or 7 years but the increased speed and reliability that I am now getting with this computer is astonishing.  It just works!  The tall case is GONE!  Everything hooks up to a USB3 hub and the quad core i7 chip handles my computing chores like Einstein would handle arithmetic.  There is deep support on the Intel web site but it is hard to dig through.  The accompanying instructions are simple (relatively useless) hook up photos.  Perhaps the comprehensive manual is still being written.This is a bare bones machine for those who wish to build their own system.  But that's exactly what I was looking for as I've had too many machines with crappy peripherals or "on-board" components, and preinstalled crapware.  Once you get his little miracle you need to add a hard drive (M2), and RAM, an Operating System, and then attach your own I/O devices.  I use the HDMI video port, the USB3 ports for hubs, and the LAN port for my network.  Soon the audio port will feed a 7.1 sound bar and woofer.There was one major surprise - other NUC units from Intel can use an M-2 drive or a normal 2.5" SSD drive and some can use a combination of those two types but the Skull Canyon can only use one or two M2 drives.  Not a problem except I had a 1T SSD drive available which I could not use in this product.All-in-all, I could not be happier with this unit after about 3 months of operation - no complaints.
