I think Jonsbo, Rosewill and Cooltek are the same.
That's a great looking case.
Where do you live? It's definitely available here in Europe.
I currently have the silverstone RVZ01 and its a pretty awesome case. Only downside is buying a SFX PSU. The 600W Gold PSU is around $130 I stuck with the 450W Gold. There is also the similar to the RVZ01, Silverstone ML07B.
