As I'm sure is the case for many other people, I have a ton of hardware laying around that isn't profitable for bitcoin mining at the moment. Is there something more useful to do with my S1, S5, S7 that's taking up space other than a once expensive paperweight?

Is anyone having good experiences with multiminers that just throw hash power at altcoins?

I've got a few scrypt miners that I use to convert various alt to BTC regularly but my ASICs are much more high powered and efficient, is there something else to be done with them?
