I'm set to purchase the NZXT Source 220 (however, still undecided)
Here is a picture of NZXT's defautl fan setup:

This case has fan openings: 2x 120mm front / 2x 140mm top / 1x 120mm rear, and a side and bottom fan mounting location.
As shown in picture ^ is a 120mm rear and 140mm top fan; however, it looks like they are both used as exhaust fans. Interesting, could this cause some dust issues?
Fan orientation
Anyway, if I where to buy this case I was thinking about installing a single 140mm top fan and another 120mm front fan, and using BOTH as an intake fans (maybe with filters). I don't know, I suppose I could play around with different orientations. I once found an article somewhere that experimented with this in great detail, and they found that two fans (1 rear and 1 top) gave the best performance; wish I could remember what website it was.
Connecting fans to motherboard vs. PSU
I like the thought that I can control the chassis fans in UEFI or AXTU (ASRock motherboard). Whats the difference between the 4-pin chassis fan connectors and 3-pin? I know I can safely connect a 3-pin case fan to the 4-pin connector, but I just can't find a detailed explanation of the difference. And no, I'm not talking about the CPU fan connectors.
Furthermore, I was told that using a low rpm (say 800rpm) fan connected to a motherboard connection (CHA_FAN) can cause issues from cutting off the fan from even working to burning out the fan. Interesting, I have read a couple of owners manuals for some motherobards I am looking into and no-where do they explain what voltage or RPM specifications to look for. The only thing the manual says is:
"Please connect the fan cables to the fan connectors and match the black wire to the ground pin. CHA_FAN1/2/3 fan speed can be controlled through UEFI or AXTU."
