as in the floor of the case, my only question is, should i just make it an open vent, or would putting a fan in there be better.

lian-li pc-61b i might add. i was thinking of a 120mm fan.

here's a pic of the spot i was thinking about:

If you want hot air to escape, having a passive vent on the bottom is not going to work well. Heat rises so the best use for the bottom would be to let more cold air in. And a fan would be helpful.

 
It will be more likely to draw in dust too. Especially if you have your case on the floor.
 
nah i mostly want more air coming in. and i have my case up on a tv-cart, so it's definitely off the floor.
 
Something else to consider - a bottom intake may keep the air from your front intake, and
heat from your HDD's from reaching the exhaust fan. In other words, it may produce a little
dead spot in front.
There are numerous posts on this subject across the forums.
 
The best place to put one if you dont already have one, is a top vent/blowhole. Whatever the biggest size your case supports, if you have enough room inside.

My old Antec Performance Series 1000AMG, had enough room for an inside-mounted 120MM fan..which I modded and installed.

My current case, could barely fit an 80MM if I ever did mod it.. (Antec Super Lanboy)
 
well i currently have an pc61, plus a 6800gt. i actually have an 80mm fan where the floppy drives go b/c the 120mm fan wasn't moving enough air for the video card and CPU. so this mainly just to have enough air for the card to live on. i'm also planning on gettin an arctic cooler for the card too.
 
I was working on a case that has a bottom intake. The case is entirely custom. Well that is a lie. i am using a few frame parts from an Asus case I bought for this project. Actually that intake will be the only intake for this case. I'd post a worklog but I just closed a deal on a house and am getting ready to move. So it has already been packed away.
just for clarification though, it involves aluminums ducts and filters so the intakes are not pulling directly off the floor.
