Yes, it has been sold out for at while.
I've been very temped to buy the one from X-Case (been looking at it since last summer), but when I read the comments I decided to wait and see what the new revision of the case will bring, mainly because of the heat issues.
According to X-Case themself, there case is not the same case as the Norco one, but it sure does look A LOT like the Norco.
I'm in the same situation as you. I'm in Denmark. The Norco will be too expensive with vat and taxes (from US)... And a normal tower case with 3 or 4 "5 in 3 backplanes" bought in Denmark is way more expensive then the Norco/Case case. So as I see it my best option is to wait and see what the new X-Case will be like.
