Just noticed something on the Elbox site that may have been there for ages but I have never noticed it. It's an interface to connect an modern ATX power supply to a motherboard or busboard that requires AT power supply connectors P8 and P9. Can I just go to the nearest pc store and get a 400 W ATX power supply for 35 euro ?? :-? Is it that easy

:-?
