If this is just for audio, you will want/need an external usb or pccard sound card rather than what comes with the laptop. In addition, the analog output from the laptop will be much quieter and more dynamic when the laptop runs on battery as opposed to AC. Another option is to run the optical digital out from the sound card to a DAC with your system. As for laptops, I use a HP with a Philips USB Dac for streaming internet radio (128k AAC) through Winamp, or for wirelessly accessing an iTunes library from a desktop server. As for fan noise, I think the cooler pad/ventilation suggestions below are excellent suggestions.
Also, I have heard that the AMD processors run cooler than the Intel, so you might want to check that out.
Good luck.
