Micro-Star International has a booth in Taipei, Taiwan, at Computex 2013. There, among other things, it has introduced three mini-ITX motherboards.
They are called Z87I, H87I, and B85I. Obviously, the chipsets they use are Z87, H87 and B85.
The first two both have 4-phase VRM with cooling, Gigabit Ethernet, a PCI Express 3.0 x16 slot (one each), 24-pin and 4-pin power connectors, two full-size DDR3 DIMM memory slots, 8-channel audio, 802.11 b/g/n WiFi, and Bluetooth 4.0.
The only advantages that the Z87I has over its sibling is a second Gigabit Ethernet port and CPU overclocking support.
As for video connectivity, MSI settled for DVI and HDMI.
As for the B85I, it has much the same features, but 6-channel audio instead of 8-channel, no VRM heatsink, and no wireless.
All three LGA1150, Haswell-ready mainboards have six USB 3.0 ports and some USB 2.0 connectors.
