The HP EliteDesk 800 arrived with everything needed (except monitor). It had accessories of a keyboard, mouse, wifi dongle, DVI to HDMI converter. No scratches on the box and all features work that I've tested. Quiet and love the form factor, and 6 USB 3 ports. 11 performance tests by Novabench software show the machine is quite slow for an I-5 system, especially slow for GPU. Not a gaming system. The speed is not a big deal for me since I use it for surfing the internet and background tasks like video conversion using Handbrake. Plays YouTube videos full screen just fine. It is much faster than my old Celeron linux box. Might convert the EliteDesk to Linux for a "decent" operating system ;) For $90 it's an excellent deal.
