Hi
This is a really strange one, i have a HP Z420, and the USB ports on the rear look fine, but when i go to plug in a USB cable it just doesn't fit. I assume that the casing is somewhat skewed, but it doesn't look like it's been 'tampered' with. It must be the casing panel - as i can't fit a PS2 cable into the mouse slot, but the keyboard one it fine.
Does anyone have any experience of how to maneuvre this metal plate on the back?
