[Cube] Video card

[carlos]

Hello from Portugal

I receive this Cube MailList for some time now, but this is the first  
time i´m asking something, so i hope i´m doing it the right way.
I have a 450mHz stock cube, that seems to to be having trouble with  
its video card. It´s yet to determine, but if it comes to having to  
replace it, my question is;
Will a video card from a 400mHz G4 (AGP Graphics) wich is a ATI Rage  
128 Pro with 16MB VRAM(VGA/ADC) fit in my Cube??
If it does fit, will that be all?
Do i need any ROM flashing(?) on it??
Is there a "brackets issue as i´ve read about somewhere??

Thanks for any help

Carlos
