I'm with you. I love this Emac with MOS but I hate the screen. Some hacking is in order. I have a spare case, I'll see what I come up with and post pictures.
I thought that the 17" CRT of the eMac would actually be good for running EUAE on MorphOS to run old Classic Amiga games, but will have to wait for someone that has an eMac to report on that. With the limited VRAM in the eMac, I think you should be careful with how large an LCD monitor you get to use with a converted eMac to Tower project. I don't think I would try to use screen sizes larger than 1280x1074 if you plan to have multiple screens running simultaneously or you may end up running out of VRAM.
Edit: I do run my 1.5GHz G4 MacMini w/64mb VRAM on my 20" widescreen Dell LCD monitor with a 1680x1050 resolution and haven't had any problems over the last several months.
