Word
I personally have never seen a successful 150 watt HPS PC Case grow in this forum, although I do vaguely recall that there were a few people on OG who pulled it off in full server cases using cool tubes and complex ventilation systems. Personally I have a hard time controling the heat from a remote ballasted 70 watt HPS in a giant server case with a glass heat sheild and seperate cooling system for the light.
So running a 70 watt HPS in a large PC case should provide you with a pretty good challenge trying to keep your case cool, but there are plenty of people here who do it successfully so it certainly can be done if you design a good ventilation system. But if this is going to be your first grow I'd say keep it simple and go with CFLs... 80 to 100 watts per square foot should provide you with some very nice buds and shouldn't be too difficult to cool.
But if you are dead set on using a HPS in a small PC case sized grow box than they do make some 50 watt HPS lights with an electronic ballast that won't be too difficult to cool. They're hard as heck to find though so I can't provide you with a link to one, but the company that makes em' is "Lights Of America".
Good luck HK_423 and keep us updated on how your cab building goes!
