I have an old P175 w/ 48Mb RAM....QNX or BEOS?...or

[MegaVectra]

I want to use it as an internet appliance and to listen to MP3s over my LAN.

Specs:
P175
48MB RAM (can add more)
ATI Expert@PLAY 98 (Rage Pro)
SoundBlaster AWE32
3COM 3c509b NIC

What OS would be best in this situation? Speed is the major goal. WIN2K, BEOS, QNX, a LINUX distro? Thanks in advance.
