My IIfx has mostly tantalum solid-state caps from the factory (Fremont CA 1992), so I assume that the only part that will need recapping will be the PSU (its a Sony though, so probably uses high quality Japanese caps) and the two rather large radial electrolytic caps on the logic board some time far in the future.
Looking at a photo of the II/IIx logic board, it doesnt look like any of the caps are surface mount so they should be one of the easier macs to recap.
