New to growin, still in plannin mode plz help

Hi, Well I've been wanting to grow now for while, but before I start closet growin I wanted to try a "stealth" box, I have an old Stereo Speaker Box which I would like to convert into a grow cabinet, the size of the box is 18 inches wide, 13 inches deep and 32 inches tall, I was thinking of havin four CFL runnin down the back of the box but if having them on top is better please let me know. I also have two 10 inch regular house fans which I was thinking of custom fitting into the sides, one on the left bottom and one on the right top, one blowing in and one blowing out. the inside of the box would be mylar'd, later on when I have the money I was thinking of having two CFL and two Hortilux HPS Lights, I was wondering if this is a good setup I'm prob going to grow just one plant I was thinking lowryder, unless you guys think I can fit more then one plant. the front will look like it has speakers connected but it doesn't it's just to make it look more stealthy. any suggestions. tips, anything? would be appreciated
