Hello,
I'm a first time builder with all of my parts in front of me :) 

1)I have two USB connectors on my mobo (ASUS P8Z68 Deluxe) one of them says USB1112 and the other one USB1314. Which should I use if I want to connect the USB ports on the case?

2)Which SATAIII controller is better to use the Intel one or the Marvell one?

ANS 1 - if USB1112 & USB1314 are off the USB 2 Header then it doesn't matter, the USB header closet to the DIMM slots are the USB 3 headers. So IF your case has it's own built-in USB 3 use those or the USB 3.5" Font Panel. edit: looked at the manual pg 2-28 doesn't matter - flip a coin they're the same.

ANS 2 - Use the Intel SATA3 for SSD, mechanical HDD use the SATA2 ports. Yep even if you have a 'SATA3 Interface' HDD, the Intel Write speeds are faster and the Reads are the same.

I have a mechanical SATA3 HDD. Intel has SATA3 ports and SATA2 ports. You still recommend using the SATA2 ports anyway?

Yep, people buy SATA3 (6.0Gb/s) HDD's and assume it somehow makes them better or faster - it's doesn't. A HDD is limited to 120MB/s - 145MB/s which is 1/2 the SATA2 max of 300MB/s {290-295MB/s real world}. edit: Yep, to the Intel SATA2 ports, most tests I've seen with ATTO seem to show a slight benefit to Writes in your instance, and less long-term issues.

However, on the PLUS side most SATA3 HDD have a larger cache which is nicer :) 

Further, the Marvell 912X is 'shared' and has an x1 lane and real world it craps-out 360-390MB/s whereas the Intel SATA3 expect 500-570MB/s. The Marvell 918X use x2 lanes 'shared' and matches the Intel SATA3 native Read but is slower for Writes. The Marvell + LGA 1155 is only good if ALL the other Intel SATA3 ports are filled.
