300PL 65652BU

i have a 300PL running at 667mhz.. i'm in need of a faster machine and
i would like to know what type of motherboard i can use in my current
box.. i love IBM's blue/white cases and i would like to keep the one i
have.. is it possible to switch the motherboard or are the 300pl's
designed like aptivas that will only take ibm's boards?
