Rubber Grommets for Cable Management

[Norm101]

I'm using the CM Storm Enforcer and I'm working on cable management. Some of the more expensive cases have rubber grommets inside for pass-throughs that hide wires better and keep the wires behind hidden.

I think Cooler Master sold some previously, individually, but I can't find anything anymore. Is there another option or solution out there?
