Summary: Gaming or overclocking? Hit back on your browser. Let's face it, it's a boring board. But a great choice for business workstations where price and reliability are more of a concern. The CSM (Corporate Stable Model) has a longer support period from ASUS and goes through more compatibility and quality testing - similar idea to the LTS releases of Ubuntu. But unlike most 'business' products, it's actually at a very reasonable price.
Pros: Compact, full range of PCI slots (x16, x1, std), plenty of SATA ports (w/4x6GB/s), CSM
Cons: No labelled riser for case jacks (like on P8Z77-M), only 2 SATA cables included.
Summary: great motherboard and amazing response with a i5-4430. it comes with daemon tools pro on the disk (why advertise a demo), but sadly no cd key. still a great choice if you are putting a pc together it runs cool and has just the right amount of slots for a couple fans
Pros: 4th gen intel support, 4 ddr3 ram slots, great price
Cons: 2 fan slots, 4 pin power connecter can be confusing., no daemon tools pro cd key
