I have a 280-pound capacitor, four of them in fact.
Well, they must weigh something in that vicinity.
They cost $500 each, including pallet shipping.

The physically largest capacitor I ever saw in person was a PIO type
rated IIRC for a couple of uF at several kV; it weighed about as much as

In the sixties I worked in a company that made HV transformers and equipment
for power stations, railways, etc, now the caps I have seen in the HV test room
were alsmost as big as me.
Soem of the transformers required a ladder to climb on those.
The caps looked a bit like these:
