Ok, My old cheap case has bad airflow so I removed the glass plexi and made a little fan mod for the door.

I've connected all the fans together. My question is, will a single 4 pin connector from the psu
power these fans all connected together?

The stats on the box of a fan is 12v, drawing 0.20A

The psu that I have coming is an Antec 650W neopower, 3 12v@19a's.

Said mod

said all pins connected, I plan to use a single 4 pin on this, is this bad or ok?

If this is ok... what would be the max of fans I would be able to use...
 
Should be fine. Fans don't take that much power.
 
Lots. If lets say the entire 19A rail was dedicated to that type of fan, you could run 95 fans on that rail. That'd be nuts but going by numbers alone that's what you get!
 
really....

If that ocz vendetta didnt stick out too much, I would've made a wall of these..

More fans are not always better, you might be hurting yourself with this setup, or at least adding more than the needed amount of noise, if you have the normal front intake and rear exhaust you could end up starving the HSF of fresh air from the intake as it's all going to be exhausted out the side.

Theres no front intake, because the holes are crap and won't get much air in. We'll see how much noise these guys make. And these fans are pushing air in, not out, I guess I pointed the fans the wrong way eh.

The side with the frame that attaches to the fan hub should be pointing in the direction that you want the air to blow.
 
Doubling the amount of fans you have will only increase the noise by 3db.

Well, rather than adding allot of fans to the side, why not mod the intake and exhaust you have? Break out the dremel or metal sheers and cut out the stamped grills, not only will it flow more air, but can also make a night and day change in turbulence noise. Proper and balanced air flow will almost always work better than brute force air flow.
