Instead of using water, I know of a couple of high end industrial computer systems that have the motherboards submerged in chilled mineral oil. Mineral oil replaced PCB's in pole transformers. It's inert, and has a fairly high dielectric strength. It's also used in electric radiator heaters. if you can weld aluminum, making a case wouldn't be a problem. Use 0-rings, or sealant, around each opening, and liquid tight glands for cable entrances. This would give you a fairly bulletproof system, and you would have a fairly nice passively cooled system. The MB would heat the oil, and the case would cool it. As for the LCD, I've never seen one submerged in mineral oil, but I don't see why it wouldn't work. Just seal the glass of the LCD to the opening in the case. The only downside would be maintenance. -- -Mark Ne M'oubliez ---Family Motto Hope for the best, plan for the worst ---Personal Motto ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
