Even taking the time to create the normal letters (a, b, c, etc.) would be a complete waste. Dell's XPS line is their gaming line, and as such designed an appropriate label. Any future gaming systems they have will be either 1.) released under the XPS name, keeping the same three letters, or 2.) released under a new name, in which case they'll want to differentiate between the new name and XPS and create a new design for that new name.
So yeah, there is almost definitely no font for you to use. Why not just draw the text yourself, as opposed to relying on a font?
