I am trying to find the newest version of the Antec 900 - the one WITH the holes for water cooling in the side panel. Does anyone know which retailers have this version? I have contacted several of them and they all say they don't know which versions of the product they have. Please help!

Where did you here this? I can't find any info about the 900 coming with water cooling ports.
I know my P180B has them and the box it came in said ver 1.1, but I didn't know the 900 was adding the same thing.

yes it has holes for water cooling. Anything you buy at a store will have the case with the holes.

I got mine at the computer shop near me, and the water cooling holes are not on the side panel but on the back of the case.
