Hello. I was reading about a new form factor called BTX. naturally it won't fit into the standard ATX case. What I am worried will we have to buy new cases and new everything after we spend hundreds of dollars on modified cases we allready purchased or built ourselves? or will the ATX be here for a long time along side of the new BTX ? please let me know I am looking at purchasing a Thermaltake and really can't see spending all that cash on a case that will be outdated soon. Thanks Tom.
