First of all, welcome to LQ. Glad you were able to join us.
With only 128Mb ram, I'm gonna say one of the lightweight distributions like Puppy would work. Your Nova has 3 USB ports so download a copy of flash-puppy, http://www.puppylinux.com/flash-puppy.htm
onto a pen drive and stick in in and try it out.
Please come back and tell us how you made out with the Nova and whatever OS you put on there.
