Default downside of using computer bus capacitors?

Computer grade buss (screw connector) capacitors seems to be readily available, both new, new-old-stock, and used. These seem to be well matched to what you need for an amp power supply in terms of capacitance (5,000 - 50,000 uF or more) and voltage rating (e.g. 50VDC - 100VDC or more).

The screw connectors seems to be practical for connecting wiring or bus bars.

What's the downside if any? What is the relative ripple current and ESR for this type of cap versus the usual large snap-in variety?

For instance, currently available at Mouser:

22,000uF 63V screw terminal United Chemi-Con capacitor $16.50ea QTY1

Generally the esr and ripple rating are slightly better than "normal" commercial/industrial grade capacitors.
Generally they are more expensive than those as well, but usually not as expensive as the "exotics" that are offered to the audio builder.
Sometimes they are bigger.
