surprise, as the motherboards all use the 875 chipset and they look more or

that some boards have integrated ADI sound and some do not.

The CPU I took out was rated 2.6HT, and it had an all-aluminum heat sink.

The fan-and-green-cowl for both types of heat sink is the same... Ben

The heat sink with the copper heat pipes will only fit one way round, that
is the side with the copper pipe loops is towards the memory modules. * If
you try and install it the other way round the copper pipes will foul the
capacitors that are lined up alongside the plastic frame.... Bruce

thanks for that info
