DIY Question, not even sure if this is allowed here. Basically, I have an old iMac G3, tray loader. I want to be able to play my Nintendo 64 on it since it looks better on CRTs, and I think the G3 case looks really cool. I know that natively these computers don't have video inputs. Would it be possible to put a crt from an actual tv inside the case or are the screens an Apple-specific size?
