CM Stackers 830 Evo revisions/model numbers question

I'm considering getting this case, apparantly there are 2 different model numbers for the 830 evo: RC-830-KKN3-GP at Newegg:

http://www.newegg.com/Product/Product.aspx?Item=N82E16811119122

and RC-830-KKN2-GP at ZipZoomFly:

http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10005351&prodlist=yahoo

The latter version is $60 cheaper yet looks indentical, is it inferior to the one at Newegg?

I read that this case has went through a revision: 2 water-cooling holes were added to the back of the case and the mobo tray has a cutout in it for cable-management. I dont know if either of these are the new version, judging from the reviews at egg i think they are selling the older one but some people did get the new version thouigh. Anyone know about this?
