Yeah, that motherboard is awesome. I'm using a very similar setup, though with a discrete graphics card (GTX 660) and it was very painless (it's Flonne in my signature; this box replaced Etna, which is now running Windows 7 for my mother-in-law). Once I had it up and running with Multibeast I decided to see if I could follow the Clover guide. Ultimately, I built a 1TB HDD + 256GB SSD Fusion drive and have a 100% native /S/L/E folder, with just the Realtek audio and ethernet kexts along with FakeSMC on the EFI system partitions of the two drives. Toleda recently redid the ALC Clover stuff to be even more foolproof than before, so it's even easier to set up. Bring on Yosemite's official release - this Haswell box is ready for it.
