no problem!
the connector has 1 yellow wire, 1 red wire, and 2 black wires
yellow = 12v
red = 5v
black = ground
(this is standard and i've never seen anything different but just in case look on the side of the power supply, it will say which colored wire carries what voltage)
on the side of the power supply it will say how much power is available to each voltage (mine is 350w and supplies 10a worth of 12v power)
now, what you'll want to use are 12v fans they're about $2.50 each for 50ish cfm and about $5 for 80-100 cfm
once you're picked your fan either wire on a connector OR just cut the connector off the PS and hardwire the two together (i use connectors for ease of movement)
the only thing you should watch out for is that 12v fan may only have 2 leads (should be red(power) and black(ground)) so you're going to want to take the RED wire from the FAN and connect it to the YELLOW wire on the POWER SUPPLY
if you connect the RED wire on the FAN to the RED wire on the POWER SUPPLY you'll only get 5v to that fan and 5v is not enough to power a 12v fan
you would not believe the air movement potential one power supply has, the fans i will be using will draw 0.240 amps providing 46 cfm each @ $2.50 each
so if i max out this power supply (use all 10 amps) with JUST these fans i'll have 40 fans moving 1840 cfm for a total price of $100 for the fans
i know this isn't as efficent as a 1840 cfm blower, but try to find one of those for under $100

sure you can, there is no need for the fans to be IN the case or for the case to be IN your grow room (mine is in the room now to provide heat but in the summer i'm sure i'll have to move it out)
if you want to put it outside your grow room i'd recommend hard wiring an extention onto ONE of the leads from the power supply and just split it once inside the grow room 14 gauge wire will work fine for this application as well as extending the cord from your ballast to your light socket (assuming you put your ballasts in the case as well)
