In general ALL A1200 Turboboards fit into the Desktopcase. Only exeption would be the Blizzard 1240 and maybe some DCE made Blizzard1260 due to an upright SIMM-socket.
Usually only 040er and overclocked 060er cards need a fan. For a 25MHz 040 you might get away with just a passive heatsink. That`t the approach the Apollo1240 takes with the processor faceing inwards so you can still close the trapdoor (though it is not recommendet, as the 040 even at 25MHz generates a lot of heat)
