Rarely do motherboard vendors dish out mini-ITX form-factor motherboards targeting the overclocking community. There's little space to squeeze in the bare essentials, but nothing is impossible, if there are competent designers at work, a case in point is the new Z68-ITX WiFi from ZOTAC. Based on the Intel Z68 Express chipset, this board supports LGA1155 Core i3/i5/i7 Sandy Bridge, and future Ivy Bridge processors, supports their integrated GPU giving you access to Intel QuickSync technology, as well as a suite of overclocking options.

To begin with the LGA1155 socket is powered by an 8-phase digital-PWM power design that uses high-grade PWM chokes made by Pulse, and in all probability, a Volterra PWM IC giving you precise voltage control as well as vDroop protection (high-precision load-line calibration). It also uses server-grade high-C capacitors. The PWM circuit takes input from an 8-pin EPS connector. The PWM chips are cooled by a large heatsink that sends some of its heat to the heatsink cooling the Z68 PCH, over a heat pipe.The lone expansion slot is a full-bandwidth PCI-Express 2.0 x16 wired to the processor. Memory is care of two full-length DDR3 DIMM slots, supporting dual-channel DDR3-2133 MHz memory. Other overclocker-friendly features include button controls for power/reset/CMOS-clear, an LED diagnostic display, and two 4-pin PWM fan headers.

Connectivity is by no means compromised to add overclocking muscle. There's WiFi b/g/n wireless networking, dual gigabit Ethernet, 8-channel HD audio, USB 3.0, display connectivity including two HDMI 1.4a ports and one mini-DisplayPort; storage connectivity including two SATA 6 Gb/s and two SATA 3 Gb/s, supporting RAID and Intel Smart Response technology.
