who makes the 40.1? ( yeah i know IA ) i want to know if there are any other company's that have the same heatsink as the 40.1
x2i believe its a zenon board. about 90% certain
the IA20.1 & Atomic 1800.1 are the same boards, different parts. very similar sinks & such.Atomic had a look a like heatsink to IA
