Summary: The P8H67-I Deluxe manages to squeeze more features into a Mini-ITX form factor than an awful lot of full-sized ATX mobos spread across a much larger surface area. As far as I can tell, the only sacrifices Asus has made are dropping a couple of internal SATA ports and swapping traditional DIMM slots for notebook-style SO-DIMMs.
Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete.
Pros: UEFI Introduces Graphical User Interface BIOS replacement, Integrated Atheros b/g/n WiFi, MemOK! Increases memory compatibility for bootup, ASUS EPU increases energy savings, NEC-D720200F1 SuperSpeed USB 3.0 controller, ASUS BT GO! Bluetooth adapter
Summary: Compared to the Zotac H67-ITX , the P8H67-I has a touch higher idle power consumption, but the difference is trivial compared to the >10W advantage the P8H67-I has on load. The UEFI even allows for undervolting which could potentially make the board even more energy efficient. The UEFI is essentially the same as those offered on Asus' microATX/ATX variants, providing a fair degree of customization, at least as much as a H67 chipset board is capable of.
