For a board of this type, we’ll focus on the layout from the perspective of a system builder, as opposed to a home user or enthusiast.

There are two minor layout issues to be aware of. Firstly, the standard 20-pin ATX power connector, and 4-pin ATX12V connectors are located on opposite sides of the board, so make sure the power supply and case you’ll be using can accommodate this. Most smaller microATX cases should be sufficient. Secondly, larger AGP cards will block the DIMM clips, and prevent installation of memory once the video card is installed. Just something to be aware of if you’re about to build a hundred of these.
Those minor issues aside, the rest of the layout is clean. There isn’t a whole lot of real estate around the PCI slots, however full-length cards are rarely a concern in this type of system. While on the subject of PCI slots, the board features three of them, and a single CNR expansion slot. With the on-board LAN and audio, however, two PCI slots would be more than sufficient, and the CNR slot is probably totally useless.

Three fan headers are available, though we usually recommend connecting case directly to the power supply, in order to reduce loading on the motherboard. This can help avoid repair jobs due to burned out fan headers.
No jumpers require setting prior to installation. CPU multipliers are auto-detected, and the BIOS is used to specify whether PC100 or PC133 SDRAM is being used (naturally PC133 is the better option).
