66MHz and 133MHz PPC BeBox
The BeBox was only ever shipped in two models - one with dual 66MHz
PowerPC 603 CPUs and one with dual 133MHz PowerPC 603e CPUs. It is
rumoured that there existed a prototype 117MHz BeBox, but I have not
confirmed this. It is known that other speed prototypes existed,
namely at least one dual 120MHz 603e and up to 5 dual 200MHz 603e
BeBoxen.
