This is an old AT desktop that I turned on it's side. It's my 4-year old son's computer. He picked the window design and the colors (he wanted rainbow colors). I removed the little fan on the heatsink, suspended an 80mm L1A over it and made the legoman grill (posted before). Since I decided to use the grill on a fan, I drilled out the holes a bit to improve airflow. It's a K6-2 350 so cooling's not an issue. I cut a window in the PSU and added a ccfl to light the case up.
/me grabs old legomen and begins hacking them into fan grills! but man, that paint job looks awesome!
I think the paint job and that window design makes it look pimp. I dunno, it just looks awsome. I forgot to mention, that mouse is sweet. You should paint the keyboard some more though... Like blue function keys and yellow for the rest? I dunno, but the beige keys don't look quite right...
If you paint the keys colour code them some how.... it might help him to learn which keys do what... remember children learn well with colours as it helps with they're progression through the stages theorised by piaget.
