Well you can also go with the soyo dragon models, they have the 2 raid and the 2 reg ide channels as well and also has onboard audio with the c-media chip. Its actually a pretty decent sound unless you are uber picky about your sound (it is 5.1 compatable) and it also has 10/100 Mbps ethernet on board. It does cost a little more but you don't need to get a sound card or a raid controller or a ethy card. also the platinum versions look sweet =+]
There is a kt266, kt266a, kt333 and kt400 for athlon and some for Intel as well, not sure on the chipsets on them here is a link to the kt333 model (one I have)
