More info on the room. Is this a closet? Or is this the space you are using in a bigger room? How many plants are you going to try in that space? Are you looking to cool the area only or do you want to control odor as well? More details would help me give you an opinion.

i agree about know the circumstances, but i would say, that unless there perfect i would not stuff a 400w hps in there it is going to give off heat, so unless you have like 6" inline fan made to take heat off of it i would try. you will probable end up burning your plants.

look into t5 lighting 2ft. 4 blb its goo enough to start seeds and clones and will take it till it needs to be flowered. which then you can replace the bulbs for flowering.

My 400w cab has about the same square footage and I use a S&P TD-150 (5") fan. Its rated 197 cfm's on high and it puts my temps where they need to be and in a closet. Its a bit bulky so I had to mount it on top and have it suck the heat from the box. 400w will need roughy 200 cfm's just to cool the light. Do a '7th1der' keyword search and check my cab thread to get a visual. Or I'll try to post one later when I get in front a computer.
