Is it absolutely impossible to implement a cooling solution that will allow using two X1900 in Crossfire mode ? How does one go about doing that ? Is it a much better idea to wait for a Crossfire mATX board to use with a SG-01. I've postponed my SFF dreams so far and I want my next upgrade to be a FF change so it should be worth my money. I am thinking about selling my Mobo, Case and PSU and getting one of these Shuttle's. The timing seems to be just about right because I will buy a new PSU and Mobo anyway so if I can make use of my X1900 CF in this Shuttle I will choose the Shuttle or it's back to Midi Towers.
