Introduction
The Intel H61 chipset has a lower cost compared to the H67, but has one primary disadvantage: it does not support SATA 6Gb/s. While this may be a concern for fast SSD hard drives, the overwhelming majority of drives used in our Echo I and II will not suffer any performance hit by using SATA 3Gb/s ports. With our decision made to move to the H61 chipset, we looked at the available boards from Asus and decided on the P8H61-I. This motherboard uses full size DDR3 RAM sticks, as opposed to the SODIMM's used in the P8H67-I Deluxe. As the P8H61-I is not a deluxe version, it does not have wireless built in, but the extra cost savings means that a separate USB wireless adapter can easily be added. One large advantage of the P8H61-I is that it features two internal USB 2.0 headers which is ideal since the Antec ISK-100 (used in our Echo I systems) has 4 front USB 2.0 ports which need 2 internal USB 2.0 headers.

ConnectivityConnectivity covers the external ports on the I/O panel, the internal headers, the PCI-E slots on the motherboard, as well as the networking options. Starting with the external and internal ports/headers, let's take a look at what is available on this motherboard:
For the internal SATA connections, there are 4 SATA 3Gb/s ports using the Intel H61 chipset. There is no ESATA or SATA 6Gb/s ports available on this motherboard. Networking on this board is limited to a single gigabit RJ45 LAN port. Normally we would discuss the PCI-E options available on a motherboard, but on a mini-ITX motherboard, there is no need to go into great detail. This motherboard has a single PCI-E slot running at PCI-E 2.0 x16 speeds. | |||||||||||||||||||||||||
Motherboard Layout
On a motherboard this small, not everything can be laid out perfectly since there is so much hardware that needs to be crammed into a small space. Considering this, we only have a few minor concerns with the layout of this motherboard. First, the 4-pin ATX power plug (#2 in the diagram) is quite a ways away from the edge of the motherboard. This means that the power wires will need to be routed over the chipset heatsink which will very slightly reduce the airflow around the heatsink. Second, the SATA1 plug (#4 in the diagram) is oriented opposite of the other three plugs. This will not cause many issues with cabling, but it does mean that you cannot route the SATA data cables for two devices completely together. At some point, one wire or the other will need to twist in order to be oriented properly to plug into the SATA device. Again, both of these issues are very minor and will not at all affect the performance of this motherboard. | |||||||||||||||||||||||||
