Casing and upgrading
As the 800 G2 is a business PC, it has a very plain black casing. It's very sturdy though as it's made out of thick metal, yet it's also easy to open up. Twist off one screw and the top plate slides off to reveal the interior.

Our review unit came fitted with a fast 128GB NVMe M.2-based SSD. If you want to fit a bigger SSD, you'll first have to remove the combined cooling fan and cage for an optional 2.5in SATA hard disk that sit on top of it.
