Help plz. Cupboard growroom

I have a cupboard L 1m W 1m H 2m. have bought a cool tube and 600watt hps. im thinking of using a computer fan to blow cool air into the area and a computer exhaust which will be placed infront of a hole into the ceiling. ( behind my cupboards i have a chimney im thinkin of makin a hole into to connect to my exhaust. Any ideas how to make this more effective and cheap. Would like to grow 4 plants. im a newbie as u can see.

two computer fans are not going to provide near enough venting for a 600w hps. you need wayyy more air circulation. you probably will need to get a vortex fan of some sort..

IS ONE INTAKE FAN AND ONE EXHAUST FAN ENOUGH..... ive read in some links u should have a hole at the bottom of the cupboard on its own....without a fan

chimney isnt working its been out of use ever since we moved in.
