Sourcing (very) cheap used InfiniBand hardware

[Jamie White <jamie@jatos.co.uk>]

Hi

I want to obtain some InfiniBand hardware (switch, and PCI cards for 
about 4-10 PCs), not greatly fussed the age, speed or state of it, 
providing it works.

This is for what is at the moment personal projects and experimenting.

When I say cheap, I mean at most £400. Anyone know way I could manage to 
get hold of this?
