I was looking for some cheap feet to get my case off the floor, I thought about the same type of casters, but was worried that I wouldn't be able to set the case on a table. It would suck if someone bumped the table just enough to get the thing over the edge . . .. I used four door stops instead. Sounds silly? they look great, even match the case color almost exactlly. They do the job quite well, too.
