Over at Computex eVGA was showing an mATX design X58 motherboard as well.
The product is labeled EVGA X58 SLI Micro with SKU 141-BL-E756. The board is pretty spiffy and comes wwith two PCI-Express x16 2.0 slots that allow for dual-slot SLI cards.
This X58 SLI Micro will have a 6-phase analog PWM design with a single EPS 12v connector. As expected, the board comes with six triple-channel DDR3 1600MHz slots, six SATA II 3.0Gb/s slots, an onboard LED for POST codes and temperature monitoring.
