As long as you do not need much expansion you could put some of the RAM from the 7100 into the 6100 and use the 6100.(they both use the same 72pin in pairs of 2 right?)
Alternatively, I have not seen the 7100 case's innards but if it is anything like the 7300 case(prolly not much knowing Apple) then you might be able to stick both 1GB HDDs in that.
I personally would go for maxing the RAM in that 6100 though. It has that G3 and the AV card as well. 7.6 would be pretty nice on that G3.(assuming there is compatible software for it in 7.6)
The only reason the 7100 would be better in my opinion is possibly more room inside, more nubus slots and more RAM slots. The 7100 case is also uglier in my opinion.
