Need Case Fan Advice

Hi guys, I'm new to cooling systems, I've read around the forums a little bit, but I have a couple general cooling questions

1) What is the advantage of connecting the fan to the MOBO over PSU? I believe I've heard RPM control through MOBO, but would that imply that a PSU always runs fans at full RPMs?
2) I have this MOBO (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131837) that only has a few chasis fan connectors, but between slots on my case & CPU cooler, I'd like to run 7 120mm fans and 1 200mm fan. Is it possible to connect them all to the MOBO? Will there be a power concern? What is the best adapater to buy, and will it support controlling the RPMs on all of them?
3) I have this case (http://www.newegg.com/Product/Product.aspx?Item=N82E16811139005). For intake, I am planning on putting a 200mm in the front, 4 120mm on the side. For exhaust, I am planning on putting 2 120mm on the top and 1 120mm on the rear (with my h60 (I know it's not the best cpu cooler) radiator attached). Would anyone recommend a different intake/exhaust setup? Would it be worthwhile to sandwich the h60 radiator between 2 120mm fans, both blowing out?
4) I plan on buying these fans:
7x http://www.newegg.com/Product/Product.aspx?Item=35-553-001&nm_mc=EMCPB-102014&cm_mmc=EMCPB-102014-_-PB-_-Item-_-35-608-017&et_cid=11703&et_rid=1092328
1x Some 200mm (Not sure which yet)
It seems the 120mm are quiet enough & moves a decent amount of air. Any suggestions on different 120mm or a good 200mm? I know the 200mm cannot be very thick, haven't measured yet, but I had bought one in the past that was too thick to fit in the front 200mm fan slot.

Any information is appreciated, I'm excited to see how much I can reduce my temps! Currently my i5-3670k is running at 72c while under game stress, as my cooling sucks, and I believe the fan that game with the h60 is failing. So, whatever happens I'll come back with my before & after HWMTemperature logs.

Thanks All!

1) Yes, if you run them off the PSU they operate at full speed.
2) You can buy some fan splitters that attach to the motherboard fan headers, but given that you'll need 3/4 you may as well just buy a fan controller

3) Doesn't the case come with a 200mm fan on the front? I would just have a 200 on the front, dual 120's on top and 120 on the rear and put the clear side panel on. I doubt that you need quad 120's on the side, unless you live in a sauna. You could try a push/pull configuration on the H60 and it might reduce temps a bit but 72c isn't so bad for a 3670k under load.

4) To control the fans through the motherboard you need PWM fans, otherwise they will just run at full speed. If you run them though a fan controller you can control the speed regardless, but running PWM fans though a voltage fan controller can damage them, running voltage fans though a pwm controller is fine. The Sentry 3 is a PWM fan controller. As for fans I like the BitFenix Spectre series, they are a pretty good balance of air flow and noise.
