I have an Orb but I am not voting here as I have no basis to compare with and this is a brand new machine, still being built, and is my first attempt at OC'ing.
For another source of cooling, try Plycon at:

I was going to buy my Orb there until I came across one at a local computer show. They list quite a few choices and have many case fans and grease etc. I can't comment about how good or bad the prices are but a cheap price on an out of stock item is useless.
Good Luck!
