I use my A2000s as hosts for bridgeboards and playing/testing A500 games, as well as for testing my Prisma card (playing mp3s on a 7MHz 68000 Amiga 2000 is cool

).
My main home A2000 has a graphics card, SSD, GoldenGate bridgeboard and 68030 Apollo accelerator: it lives under the main telly for 40" gaming goodness
