Home experimentation

Hi,

I am interested in setting up some Myrinet experimentation at home because
this is the sort of thing I enjoy doing with the longer winter evenings...

Can someone tell me whether there are any second hand or auction sales of
inexpensive outdated kit or if any is being currently throw away?

Specifically I am after this kit rather than suggestions that I use
traditional ethernet technologies as I already have those in place.

Cheers,

Jon.
