What light should I use?

I currently have a micro grow pc case for veg and I am in the process of building a grow box for flowering. The dimensions are 36" (w) x 24" (d) x 60" (h).
I plan on buying an HPS lighting system but I have some concerns about heat.
1. Should I go with 150w / 250w / 400w?
2. Should I get one that has the tubing connectors and build an inline exhaust sytem?
3. Should I get one without the tubing connectors and just build a passive intake and exhaust for the box using high cfm pc fans?

PS. I will be adding a bunch of cfl bulbs for side lighting.
