If you are at a table, stick the PC under the Table if possible... It works well with mine.

Hot Air Rises. ;)

Re: How safe to overclock?
 

Well, I'm at a desk, but my PC puts the hot air out the front and is supposed to suck cool air in through the back, but... because it's in a cabinet with a the back sealed off, the hot air coming out the front rises hits the top of the cabinet, and while some leaves, some of it goes back and gets sucked in, and it doesn't really get cool air. So, I'm trying to come up with a way of getting a good airflow going.

Place a Fan at the back possibly...Or turn it around, but that would be too inconvieniant.

ATX cases are designed with the intent that front, bottom and most side fans are to be used for intake, while rear and top fans are meant for exhaust.

It's also (for obvious reasons seen here) a bad idea to put a computer into an enclosed cabinet or hutch, and and equally bad idea to put it on the floor.

Take the computer out of the cabinet or cut the back out of the cabinet. You simply can't safely run a computer in a closed space like that.
