It may seem like a good idea but over all a Waist of time and money as the power consumed by the computers would outdue the amount of CPU power you get from old/ crappy computers. crappy computers won't provide enough CPU to hash the amount you need to turn a profit from the amount of power consumed by computers.
When it comes to minning you need a good minner that has high amount of CPU but consumes less power. this is where most people make this mistake when it comes to mining thinking I'll just go get a bunch crappy computers to mine. It would take beyond you're lifetime to turn a profit.. Plus bitcoin is getting harder to mine with the hash increase to get a single bitcoin meaning if you want to get anything from mining you got to be willing to pay the price to get something that has a damn GOOD cpu power.
