The pwm hub you've put into the CPU fan header? It would be nice to set your own fan curve up for the fans, I wrote a short guide for speedfan which I'll link you later as I'm on my phone ATM. However if you can't be bothered, I imagine the board will do a good enough job on its own.
LEDs.. The bitfenix and nzxt ones are supposed to be good. There's also the RGB NZXT Hue which is RGB.. obviously and mounts in a 5.25 bay. If you know how to solder, you can get yourself an RGB led kit off the bay for about £15 and that comes with a cool remote where you can change brightness, make it do silly flashing etc. I'll link you to that guide too. The NZXT hue comes with a 2m strip, the bay led kit comes with 5m
