All the necessary information to convert eMac ATI graphics (800MHz and 1GHz) is now in one place:
It runs either totally headless or with one/two external displays and needs just +5V and +12V power.
I know slick case would add to impact but I'd rather share details as they appear than wait for the case to show up.
I am thinking about old CD player case...
If you use this information for you projects, let me know and I will link to your page.
