You're right about the Rev. 2 B&W G3 :
(from http://www.lowendmac.com/ppc/g3c.shtml)

The Rev. 2 b&w G3 uses a different motherboard, has an additional drive bracket,
incorporates a new IDE controller chip (marked 402), and includes a faster 
version of the ATI Rage 128 video card. 350 MHz and 400 MHz models may have 
either motherboard; 450 MHz and faster versions always have the Rev. 2 board 
from the factory. The new IDE controller improves slave drive support and solves
a drive corruption problem.

When buying a blue & white G3, insist on getting a Revision 2 system. The best 
way to make sure you're getting a Rev. 2 motherboard is the "402" marking on 
the CMD646 IDE controller chip.

I'll check and see what I've got.
