 grow box build, from 2X4's to finished grow setup

so I have grown a good number of times outdoors but because of my living situation now, I have to do a grow box... I started out with some scrap 2X4's and made this 4'wX4'hX4.5'l box yesterday;
I have some siding I'll use to close it up with a couple vents for air exchange, I also have mylar sheets to cover the walls... I was thinking about starting with a 4' 8 bulb T5 setup with supplemental LED lighting, what would you guys say about my setup so far?
I plan on using soil since I'm most comfortable with it, I have plenty of nutes I used before so no worries on that...

Are you going to have some active ventilation?

yes, I was thinking a couple 8-10 inch fans placed on the bottom and a passive vent up top

Inline fans? If so that a lot of fan for such a small space. Also you want to vent from the top, and have intake at the bottom, this way you're venting the hot air out and bringing cool air in.

It'd be better to suck air out of the room from the top. How many CFM's are the fans.

I haven't bought them yet, I was hoping at least 200-300 CFMs per fan

That's a huge amount of ventilation for that space. 2-3 times the CF is the goal, I mean more is always a good thing, but at some point you aren't getting any benefits from increasing it past a certain point.

This fan would be more than sufficient for that small of a space.
