Hi Orange
The 1B motherboard I have is 390mm long x 190mm wide. With the back ports its 200mm wide in the shielding. So it looks as if it will not fit in that tower. I think there is a different motherboard version were the piece with the mouse and joystick ports on, are on a seperate piece pushed onto the rest of the motherboard. So that would reduce the length to about 320mm. If I recollect correctly you could get an adapter to turn that bit through 90%.
