Been working with my "new" used mini HP and am very pleased.  Fast delivery, easy setup, and, great performance.  I'm in the IT field and finally replaced my HP/Compaq notebook after several years of reliable use.The Mini's performance with 16gb Ram and Solid State Hard Drive is a huge improvement vs my older notebook in every way.I comfortably recommend this technology.  The CPU is running very cool and should last a good long time, as should the solid state hard drive.  A definite "Buy" if your in the market for a used computer.One Note:  I did have issues with my wireless mouse.  I was able to correct by locating the mouse dongle and wired keyboard to the front USB ports.
