Knoppix is really great/awesome.

I'm using an Asrock 939 dual-sata2 board with an AMD64 X2 3800+ and Knoppix 4.0.2 booted it as SMP. Two Penguins instead of one. Now all I have to do is find out how to get FedoraC4 to present me with an SMP kernel on my 80GB HD (master on IDE1) and then get Grub to let me boot from Knoppix on my 20GB hard drive (slave on IDE1).

AMD 64 X2 3800+
Thermalright si-120 Heatsink with 120cm fan.
768MB pc-3200 ram

Not a speed demon, but stable. Knoppix made the installation easier. I was able to check out the system before I let Fedora boot up the new equipment.
