Well, I've tried to sell and get rid of that AIO, and shipping seems to be the killer there. The CRT Is nearly hosed and it would be better to re-case the mobo... Anyway, How much room is actually in the CRT portion of the AIO? I thought about making a MacQuarium out of the shell, and ATX or hacking the rest of the system into another case. Any suggestion on what thickness of material I should use, standard plexiglass or acrylic, types of sealant, etc..? Theres enough room underneath to put the pump and power supplies, and I could even make the lid a fliptop for easy access. Any info or ideas would be great.
