So I still love the iMac G4 design, but obviously they're so dated it's hard to use one as a primary work machine these days. Now I know the extreme route would be to strip every single piece out of the case and build my own computer using the G4 case, but that's really bloody extreme. Is there an easier/cheaper way to upgrade a G4 to be a semi-decent machine? The processor appears to be the biggest performance problem from what I can tell, which obviously can't be removed without further changes. Okay so through writing this I have realised I am slightly more clueless than I thought. Just any tips, advice or feedback on my wish to get a G4-looking, modern and useable computer would be nice.
