This small form factor (SFF) fits my home office desk perfectly and looks great! It's a 2018 model HP Compaq Business Pro and has every feature I needed in a fully business capable device. An intel i5, 500 GB SSD, pre installed Windows 10 Professional OS, DVD, Wi Fi , Bluetooth and importantly, 4 -2.0 USB and 4- 3.0 USB. It came with a USB 600 Mbps Wi Fi adapter and good quality wired keyboard and wired mouse but I bought a Combo Logitech wireless set for convenience and a 1200 Mbps Duel band adapter. Also purchased and downloaded with no issue whatsoever, 2019 MS Office Business Professional Suite. All this for under $400!! And both the sellers and  Amazon's guarantee should they ever be needed (don't think so!). I am really pleased and will replace my 2011 HP laptop with a recent Certified refurbished one next month. I no longer have any apprehension about Certified refurbished machines.  Bob F.
