I re-learned an important lesson today. Think before you do something permanent. I took a board of wood (a failed attempt of a CP panel), mounted the computer on it and some L-brackets under it.
Tested it, the graphics card gives me the XP blue screen of death whenever I start a game in MAME. Replaced it with an older one which has a very loud fan but works.
Had much fun balancing the board inside the cab, marking the drill points and screwing it in. Took about half an hour, the computer fit perfectly.
Except, of course, for the fact that I placed it too close to the rear panel. Computer fits, cables that have to go into it don't.
You know that Michael Jackson song 'Scream' which starts with Michael screaming ? By now I can do a resonably good imitation.
Took the computer out again, mounted it further in, managed to ram a quarter-of-an-inch splinter under a fingernail. Fun times. Now the cables fit aswell.
Fired everything up, now that the computer has a nice new home, the sucker won't boot. Michael time again.
So, instead of finishing the cab today, I'll play around with the computer some more tomorrow.
