Can I use a US motherboard in my European Apple IIe?

Well, I'm asking this because it might be a solution to my RGB problem.

If I get a US IIe motherboard and put this in my European IIe I will get 
60Hz video, is this the only difference apart from the aux port being in 
a different place? Will the powerplug fit? Are the voltages supplied by 
the European powersupply be the same? Anything I haven't though of? 
(yes, yes, yes, no I think)

So, why...

I got an RGB card, the digital Apple RGBI card (made by Video-7) see 
previous threads. I have tried several monitors without much success. 
The best result was with a CGA 5153 monitor. I had to invert the sync 
(composite sync applied to hsync in the CGA) but apart from that it is 
just to match pin to pin on the from the 15pin of the Apple to the 9pin 
of the CGA. The problem with this CGA is that even if it is a european 
monitor it does 60Hz and the picture rolls with the 50Hz signal form the 
Apple. If you like http://home.online.no/~kr-lund/a2e-cga.avi links to a 
small 1.7MB film of the CGA test result. So if I change my motherboard 
to a US one I will get 60Hz video and the CGA should work.

If I could get hold of the proper monitor or even an analog monitor that 
is suitable I wouldn't need to do that but it seems that these are hard 
to come by and those that still have such hold on to them. Even a CGA 
monitor is pretty impossible to come by, and yes - I hold on to mine (I 
sometimes use it with a PC-AT clone with a CGA card).
