An overview of the mainboard
The IO panel. Notice the blank space between the PS/2 ports and the Audio Jacks; instead of placing legacy connectors such as parallel ports and serail ports there, Abit left it blank for some passive airflow goodness to cool the green heatsink on top of the MOSFETs. The Abit KN9-SLI is perhaps the only Nforce 570 mainboard available in the market now that sports a Heatpipe chipset heatsink, thus making the KN9-SLI a good choice if you hate whiny 40mm fans. However, do note that the heatsink on the MOSFETs and the 570 chipset does get a little warm during operation, but this should not be too much a concern as the system was rock stable throughout our testing…

The expansion slots found onboard. One thing I really appreciate about the Abit KN9 SLI is the retention clip of the PCI Express x16 slots. It is located at the top side for the first slot and the bottom side for the second. This makes it easier when removing video cards, especially when running 2 video cards. You don’t have to sandwich your hand in between the video cards to try to feel for the clip when you want to remove your graphics card.
