Need some help finding materials

[setishock]

As some you may know I'm off on another build. I'm waiting for the case and the heat sink to come in to get cooking on it.
I'm needing some plastic flat ductwork that I've only found in the UK at this place:
http://www.fantronix.com/acatalog/Square_Ducting_Fittings.html

Any one here in the colonies know of company that makes that same product line in those sizes?
And please don't tell me Google is my friend. I've wasted 2 hours on Google trying to find some thing like that in the US.

I found a bunch of places where you can get custom made ones..
A LOT of places where you special order and they install. Like heating ducts.
I searched for "Square Plastic Ductwork".

Let me narrow that down some. It has to be 55mm x 110mm.

oooooh you have to make it hard don't you.

I know you have searched your butt off. But it never hurts to have someone else do it too.

Google here I come..

EDIT:

Knowing your job, I take it you will be using these to run wires?
