This is my standard way of moving them around my building at work
It works for other computers, too
For moving multiple ones or for a greater distance than inside the building, I use a flatbed cart.
And, for all other situations, I use my car. Most Mac towers will fit nicely on the backseat floorboard of most cars. I've even managed to shoehorn two towers into my MG-one on the passenger floorboard and one on the parcel shelf behind the seats, although I wouldn't want to travel very far like that.
