Ok, so where else can I get it? Does directron carry something like this? Where would you recommend I get this kind of stuff? I saw someone used something from an auto store (chrome).... was thinkin maybe u have another suggestion?

I bought a length of 5mm silicone hose, which I slit lengthwise. Works well too, and it's cheap.

www.mcmaster.com p. 3466 item 8510k11 or others of your choice. about $0.20/ft.

Another source.

I've used the stuff from the auto stores (to line car door edges)--the black stuff, NOT the chrome. I just softened it up with a hairdryer while applying it. I've used it with success for 80mm holes and bigger...wouldn't try it for anything smaller--would probably peel off too easily from the tension.

Thanks guys. I think I'll probly buy stuff from mcmasters, assuming I do the sorbathane mod to the Zalman 7000. I'll get a buncha stuff from them at once probly.

Anyone here think it might be a good idea to have a sticky called "McMaster suggested products" and list part numbers and catalog pages of every useful product for pc case modding? Save a lot of noobs like me from posting.

You can go to a hardware store and get 3/16" vacuum hose and it will do the same thing.

In the UK, Kustom PCs sell 'Blowhole trim' which i asume is the same as C channel

Anyone from lil old New zealand managed to track this stuff down ?

I love ! reading about these great new ways to silence...its just a little frustrating after to try n track down the american and uk products taht dont make it to the southern hemisphere....

Although i did manage to source some Stretch Majic for my HDD suspension..YAY !!

This seller is good to I used them couple times and they sell international also.
