The KX7-333R features a slot layout of 6 PCI, 1 AGP and 4 DIMM. An important thing to note is that Abit has decided not to include any ISA, CNR or AMR slots on the KR7A. This is a smart decision as not many people own devices that require these slots anymore and they usually end up taking up space on the motherboard that can be used for other things. In the case of the KX7-333R, 6 PCI slots and 4 DIMM slots were included, which is something rarely seen on current motherboards.
One thing to note is that the KX7-333R features basically an identical layout to its predecessor, the KR7A. The power connectors and IDE/Floppy connectors are in the same position, as is the CPU socket and basically all of its onboard controllers. This is surely not a bad thing at all, but it was worth noting in this review. The ATX power header has been smartly placed in between the DIMM slots and the CPU socket. This is a great position for the power header because unlike previous board layouts, you do not need to run the thick power cable over your heatsink/fan unit, restricting airflow. The IDE and Floppy connectors were also smartly placed, allowing easy installation of drives once the board has been installed into your PC.
There is plenty of room around the CPU socket for any large heatsink/fan units you may be looking to install. There is also a temperature sensor located inside the socket which is where most motherboard monitor software gets its CPU temperature readings. This is not the best place for the sensor to be located as it is not directly touching the core, however, it is able to give you an average idea of how hot your processor is running.
It is also worth noting that there is a small piece of plastic under the lugs of the CPU socket. This ensures that you do not scratch your motherboard and in effect, render it useless while installing your heatsink/fan unit.
