Digital Audio Workstation Build: pls. help me pick a case

[scoring4film]

This DIY DAW builder is getting very impressive latency performance out of his z68/2600K rig and no problems with his PCI audio card...

...though it sounds like he's not a fan of the Marvell controller. Looks like his issue might be more about the OCZ drive than the controller...

I'm just about finished what might be the final build list, but I'm totally hung up on the heatsink choice and hoping someone can help me out.

The Asus P8Z68-V Pro has a PWM-enabled CPU fan header, so I thought it would be best to get a heatsink with a stock PWM fan. Seems like a simpler way to go than adding a voltage-based fan controller.

But as far as I can tell, none of the SPCR top-rated fans fit the bill in my case. Either they don't come with a PWM fan (e.g. all the Noctua HS) or if they do, they don't fit the Socket LGA1155 (e.g. Thermalright Silver Arrow/Venomous X).

Here's my best guesses so far...

1. Forget the PWM fans and get the wildly popular Noctua NH-D14 and run it at 900rpm with U.L.N.A.

2. Swap out the Noctua NH-D14 stock fans for PWM fans.

Any suggestions greatly appreciated.

thanks!

here's the mobo fan header details...
