You can do amazing things with an eeepc. So in terms of hardware anything
new will be powerful enough to achieve something useful. I personally use
a 4 core cpu with 8 GB RAM and that has enough power to do everything I
throw at it.
You will need to use JACK and depending on the distribution you choose you
may need to enable third party repos (CCRMA) to get access to all the
latest and greatest tools. Alot of people speak highly of AVLinux
