I own 2 of the HP Elite 8300 MiniTower computers.  I needed another to operate a cnc router and laser I'm setting up, so I ordered it.  Apparently, and initially this upset me, someone decided to upgrade my order from the 8300 MiniTower with i7-3770 to the Z230 with the i7-477-, and upgrade from 3rd generation cpu to the 4th generation.Like I said, at first I was upset, because it wasn't exactly what I had ordered.  But, after getting it, changing over to a SSD, increasing RAM, upgrading to a GTX 1070 SC graphics card, and getting it up and running, I decided that I like it.  It's a hell of a computer.  It may just be my next purchase, when I need another powerhouse of a computer.
