Well I have the p150 case so I know...my PSU is RMA'in as I write. I was prepared, and in this particular situation, it doesn't matter much, since I have a very good PSU allready, and its not a big problem for me to wait for the RMA to finish. That PSU will serve in my second setup for my girlfriend, who has one allready...so waiting is ok.
thanks for you concern though, I might not have been aware of the p150-issue.
The question remains though, about the Typhoon in that particular case.
