What a fantastic little machine!  This small form factor desktop performs extremely well.  I put windows 10 Pro, removed the built in admin account and clean wiped it, to rid it of some minor bloat ware, etc.it boots in less than 10 seconds to a useable desktop.  Runs everything extremely fast and the bios was easily customizable.Really can’t go wrong with this desktop.  Easy to connect and hook up to peripherals and monitor, etc.  just needed some minor driver updates (used HP driver assistant).
