@Dmaster,
I have an A2500 too. It is actually an A2000 that was outfitted with either an '020 or '030 accelerator and a hard disk when they were built so they were re-branded as A2500s by Commodore afaik. It has a real A2000 motherboard inside. Mine originally had a 68020 card and 2090a controller - long gone now.
You can safely use all A2000 expansions in it. I know this from experience. I have had just about every kind of A2000 card in mine - cpu cards (020, 030, 040 and 060), graphics cards, sound cards, networking cards etc.
