Micro ATX

In order to be micro ATX compliant, a motherboard has to have dimensions of 9.6" x 9.6" or smaller. The MSI 6147 measures in at a diminutive 9.5" x 7.5", meeting the requirement with some room to spare. This was actually a little surprising to me, given that the motherboard is based on the Slot-1 interface. Because the CPU interface is physically larger than a Socket-370 interface, it's notable that the 6147 is smaller than some of the other Socket-370 interface micro ATX boards that we've seen or tested.

Another Micro-ATX requirement is the maximum number of expansion slots, which is limited to 4. Typically, we've seen this requirement manifested as 1 AGP, 2 PCI, and 1 ISA, with a shared PCI/ISA. The 6147 departs from this model somewhat, by providing 3 PCI and 1 ISA slot. However, they've utilized a loophole, in a way, by incorporating the audio and video sets onboard, freeing up 2 slots which would normally need to be occupied just to build a functional system.
