need a little help

[REKillzone]

can somebody give me a proper list of items needs to make a box for box squats. I've started doing them and I've used like a 96-98 Compaq tower. Quite ghetto. but obviously it's too small for my ass and when i was doing 340 the other day i got scared of falling off. I know some of you guys built some power racks that are pretty nice. I need to make a strong box so i can go heavy and not have to worry. thanks

I always use a little cooler and put some weights in it so it doesn't move, works good. I used to use a big speaker that worked well too
