I've not decided on a case or PSU yet that's why I haven't involved them.
More aboutwhich motherboard better
I think that the Asus P8Z77-V is a better board. I would also change the memory from the normal Corsair Vengeance memory to the Corsair Vengeance low profile so you dont hit the bottom of the on the cooler.
I like the Asus P8Z77-V. It is better built than the MSI, and I like it's feature set.
