What about laptops? I'll bet laptops with broken screens are readily available. They could be used for configurations that need lots of slower devices. I can probably donate a dozen or more USB 1.1 to Ethernet converters so we could have low speed but complex configurations. 

I'd love a resource like this to play with. 

Thanks,
