Whats up guys, I am not sure if anyone has done this before, but I had been looking for a anclosure for a ballast I have had laying around for about a year since dismantled my reef tank, This 250 watt ballast is for a reef tank, but I plan on doing the same thing to 2 175 watt MH for my up and coming open topped planted discus tank. I looked and looked and didn't find any suitable metal enclosures , until recently I stumbled upon an old pc power supply that was not working at work, It looked to be the perfect size and it had the added benefit of a built in fan and also a terminal to get ac power. all I would have to do would be make a 3 prong disconect for the light wiring and and wire up the ballast. here is the finished product, I think that it came out pretty good, tell me what you guys think, any problems with the cap being that close to the ballast?

all comments welcomed, thank you.......

this is the disconnect out to the lamp, and dc power in to the fan

this is all the wiring in place

i insulated the hot and the nuetral wires with high temp silicone (same thing i used to attach the ballast to the enclosure)

finished product

and here we see the fan and the on off switch.

wow, that's a tight fit!
is there going to be enough air movement in there to keep the ballast cool?

thats a good question, I havent fired it up yet, so i am not too sure, but i can always reverse the polarity on the dc powerd fan and have it blow in if it restrics the flow too much. but i doubt it, theres about a 1/4 of an inch, so that should be enough........ will let you guys know....

by the way, i actually like the fact that its a tight fit, nice and compact...
