I have been running Boinc on a desktop and a laptop since the fall on a daily basis but not 24 -7. My second badge was earned for Mapping Cancer Markers. The computers are out of the box standard cpu's with nothing fancy change to them. The other bronze badge was for Smash Childhood Cancer. These are great projects as part of team gridcoin. Consider running World Community Grid.
You will meet someone with cancer sooner or later if you have not yet anyone. Cancer effects most family's and may even hit you if you live a long enough life.
