I don't think I made it clear: the bottom 2/3 of the chassis will be removed and the front bezel shortened.

Almost all of the sheet metal visible in the middle pic will have been removed during the final back panel modification.

Finished size will be about 9.25" High x 7.5"wide x 11.125" Deep.

There will only be a bit of matte black plexi side panel showing underneath the silver side panelss to match the sides of the front bezel and the matte black plexi top cover.
