Depends on your application. When I get a computer I want it to be powerful enough to run the most demanding job I hand it.
I do use less-capable computers to do non-demanding tasks. A mini would have been just fine to save the data from my weather station, but I just bought an old used computer for $25 to do that. There is no real scarcity of old used computers for short money.
