First grow box. Fire hazard?

Hey guys I just finished building my first grow box ever and unfortunately I have yet to acquire a fan but I'll pick one up tomorrow.
I used windshield reflector for reflective material and a storage box and duct tape and a power strip and 4 14 Watt CFLs.

I have a few questions :

1. it gets pretty hot above the lights and the reflective material gets hot, am I at risk for a fire hazard?
2. The hole I cut for the air/wires to escape is of course causing alot of light leakage so how do I minimize that?
3. Already cut the hole for my intake and fan but have yet to cut the reflective material covering the hole. when I pick up my fan and cut the hole how can I stop light from leaking out and illuminating my whole closet?
4. This box is only meant to veg my plants for about 30 days then I plan on moving them to outdoors (they're autoflowers). Any suggestions of how to improve this box?

Thanks in advanced and please go easy on me since this is my first grow/growbox. I've watched countless vids/read countless threads on grow boxes but I'm just not the DIY type... I gotta fix that lol

1. As long as its warm, and not hot; along with being secured well it shouldnt be a problem, all my pc boxes get really warm tops.
2. Electrical tape, or caulk. How will the air move through now though?
3. You could get a hose connecting to your fan, as long as its not straight light wont come out. Or make a box long and wide enought to cover the fan hole with another slot or hole away from the fan hole
4. Whatever works man.

Fire hazards are electrical wires that aren't capped... you are in the clear
