Well i had searched to do this some time ago but at the end i bought a second hand tower . Seeing the size of it and all the needed cuts you must do in order to fit an A 1200 inside , well it doesnt worth it . First you must get a big enough tower for the A1200+accelarator board to fit . If you want a mediator too you must consider that maybe the pci brackets want fit on a pc tower .... Also how can you fit the A1200 motherboard is a problem cause an amiga tower has a second base which on this the Amiga fits . For an unexpanted amiga it is easier but eventually if you want to have pci card , mediator board or accelarator you must search for a tower which is designed for Amiga ... Also on the gallery here are some pictures of the inside of towers so have a look at them .
