i cut a window in my cdrom, a semi circle over the back of the tray, its a rather tight fit with teh spinning mechanism so i was wondering if i have to put glass in it or if i can just leave it as is
if i where you i wouldn't think about leaving it open. because if i look to myself i am always working with fans etc. when the computer is on. so if you are working on cable management and you would have a cd or a dvd rollin .... think about the los of a finger and a repainted case for free. if you understand what i mean. maby not the best way to say it but i hope you catch my drift.
One alternative to transparancy material would be to use the clear plastic part of a CD jewel case. That would be clear and sturdy, and it should be thin enough to fit in your drive.
