A Positive Look at the Antec Nine Hundred (900) Case

[=>WiLL<=]

There's really only one way to mount those feet. Drill holes where you want them, put the screws through, and tighten.

I did not drill my mnpctech rubber case feet. I used 3M's double sided tape. Works and holds like a charm.

Do not stress yourself out by having to drill and avoid the PSU. It is not like your case gets up and walks around.

Good luck.
