A DRK masternode can also be run on a local computer. It's not recommended, and it will only cause you headaches... but it is still possible... hm....
It took me just a few minutes to set up a MN on my local computer. If for nothing else that is a major difference between the two.

"Do you have a spare laptop?"
"What about a NAS?"
"Ever thought about running a Decentralized Masternode on them?"
