Hey Ural,
Sorry for the delay but I totally forgot (I was looking at the tape measure next to my machine and wondering why I'd taken it out?!
The dimensions are;
7 3/8" wide
1 3/16" thick
16 13/16" long
The positioning on the machine has the back flush with the metal top cover.
The top of the side panel is 3mm higher than the top of the front panel.
