As the title states, I am looking to build a mining rig based on the Cryptobadger litecoin mining rig guide. I figure this will be a good entry point to mining litecoin and other scrypt-based alt coins. Then when ASICs for litecoin are available, I can just plug and play (I think?). Then possibly thinking about incorporating a SHA256 ASIC but not sure if it is possible for a rig to contain both GPUs/Scrypt ASICs/SHA256 ASICs.

Basically want advice as to how I can best position myself to be able to mine SHA256 and scrypt on the same rig? Might not be possible but any advice would be appreciated. Thanks. 

Interesting thread. Thanks for the input everyone.
