You can let MAC easily mine in the background on already existing and not fully used (v)servers with then no extra costs.
For example sometimes you got a (v)server with 2,3, ... n cores where you just use up to n-1 cores for example.
This way I run a miner on 5 vservers, 1 per vserver, which actually gives me ~ 2-4 blocks out of every 100 blocks.
For sure that depends on how many other miners take part and may change in the future.
