Rubber grommets for Cooler Master Storm Scout 2?

[AIV]

I need one of those two rubber grommets at the top right of the case back. Where can I find it?

You can pick rubber grommets up at your local hobby shop, home improvement warehouse, or RadioShack if yours hasn't converted to just selling gadgets yet.

You can also get them on eBay and Amazon.
