The customer will sadly always have to do something about an error... it's sad, but it's now in your property, there's a minimum of effort you'll need to do in every case.
Bare minimum effort:
1. Contact Amazon
2. a. Giving it back to a shipping carrier
b. Dispose of it
In the case of a server mother board, both giving it back to a shipping carrier and disposing of it is essentially the same effort (I would argue that giving it back to the shipping carrier will be more effort actually, but it's not worth the effort to argue that, so I'll say it's equivalent). That means complaining over it is petty.
In the case of "2 tons of mulch", or by definition anything "bulky to store, impossible to sell and costly to dispose of", the amount of effort isn't the same at all between disposing of it and letting a shipping carrier dealing with it. This make it complaining about it, not something petty.
