I got the Biosar. For the rebate. Manual is skimpy, but not for me - it was perfect - but only "if" you are very experienced. I had a good sound card anyway, so SPDIF was not an issue. Most people buy these board already having, or ordering a better sound solution. I had an Audigy2. Unless you run 98, or older, you don't need CD in for audio on your motherboard, in XP, the signal is decoded through the PCI bus. I always have great case cooling - never marginal, so CPU temp only was ok, perfect for me. 12v connecor would have been nice

I agree with that one, especially for overclocking. I run all fans off of a really good PSU, which is the way it should really be done, so mobo connectors are empty for me. The Biostar is every bit as fast, actually marginally faster. It beat out the Asus deluxe, and Abit Nf7-S in "stock speeds. It beat out the shuttle AN35 by a fair magin also. We all know that the Abit, and DFI lan party are the fastest when overclocking though
So, the lack og 12v is noted, but for "me" not needed. I get 2.3 Ghz just fine. But I think snow has some really good points, "if" you actually are going to use the onboard sound, and the SPDIF, then get the shuttle. Also, if you are a newer builder, and need a better manual, get the shuttle. But for pure raw speed, right next to the Abit, get the Biostar, if you are more advanced and don't need a great manual, and raid (although I have rocket raid card). Both are fantastic boards for the money.
