I've got a CyberstormPPC 68060/50MHz,604e/200MHz in my A3000 desktop. I bought it maybe six years ago, along with a CybervisionPPC gfx card. No problems with it whatsoever, best h/w I think I've ever bought, especially with the UltraSCSI3 DMA controller built-in. I was worried about heat even though it was designed to fit the standard A3000 d/t case. Luckily, I had previously cut a 2 inch square hole in the A3000 drive bay on the right side when I had a C= A3640 card w/ large heatsink. This worked out well to put a large fan over the hole for extra cooling of the cpus, simms and permedia card.
