Power Switch
A look at the power switch used to switch on/off the power supply. The computer is started using a switch covered behind the Amiga symbol at the top, left edge of the front of the case.

Amiga case – front parts – front view
The front view to the reworked front parts of the Amiga case. In the left part is added a HD-LED and the power-on switch covered by the Amiga symbol.

Amiga case – lower part
Here you see the reworked lower part of the Amiga case. At the right you can see the fence over the expansion port–now used as cooling air intake. At the right you see the (golden) shielding plate for the hard disk. This is a very thin plate, otherwise the hard disk wouldn’t fit into the case. At the rear is the power connector of the computer.

Amiga case – top cover
The reworked top cover, the signatures of the Amiga developers are still visible, only the rips are cut off.

Inner case – lower part
This is the lower part of the inner case. Here you can see the cut-out for the HD at the left side and the air intake at the right side: A large hole for the expansion port and a couple of small holes for the original air intake in the bottom of the Amiga case.

Inner case – front plate
This picture shows the front plate of the inner case with the cut-outs for the floppy drive, the CDRW, the front connectors and the cable of the new HD-LED and the power switch. The small plates are used to mount the drives in the case.

Inner case – top cover
This is the top cover of the inner case. The large cut-out is for the CDRW. IT would not fit into the Amiga case, if the CDRW would also be completely covered by this plate. A 3.5″ HD is 2.54 cm high, the CDRW has a height of about 4 cm and the Amiga case has an inner height of 6.5 cm. There is no space left if the CDRW is mounted on top of the HD.

Motherboard cable
The motherboard and all cable modified for the use in this computer.

CPU-cooler (1 of 2)
The CPU-cooler is turned by 90 degrees so the air could flow from the right (the air intake through the expansion port) to the left of the case, where the fan at the rear blows the hot air out of the case. The CPU fan is also mounted vertical to suck the air through the cooler and blow it over the chipset-cooler to the left side of the case.

CPU-cooler (2 of 2)
An other view (from the expansion port) to the CPU cooler. You can also see the cable from the serial port that is connected to the additional logic used to attach an Amiga mouse to the original mouse port of the Amiga case.

Power supply
Here you see the modified power supply for the computer. It is an ATX power supply removed from its case. The cooler are bend and the small PCB is turned by 90 degrees — using new (blue) wires to connect it. The power supply must have a maximum height of 6 cm to fit into the case.

Power supply modifications
A closer look to the turned PCB and the accordingly bend wires. In front you see a modified connector for the floppy drive. You will see later why it was necessary to modify it.

CDRW and floppy
The CDRW has to be modified. First the switch to open the tray has moved to another location (in the front plate of the inner case just below the drive). Second I had to cut-out an edge of the case of the drive to gain 2 mm space, otherwise the HD hasn’t fitted below the CDRW. The floppy drive has a modified knob and a cable to the LED in the front plate of the case.

Additional logic circuits
Here you see the additional PCB’s with the logic used to attach an Amiga mouse to the PC’s serial port. The two small parts with the wires are just switches to disable the mouse port and to switch between an Amiga mouse connected to the port or a PC serial mouse. The smaller PCB is taken from a serial mouse and is used to interpret the mouse signals of the Amiga mouse and convert them to the signals of a serial mouse. The larger PCB is an electronic switch to bypass the logic if a PC serial mouse is connected instead of an Amiga mouse.

Assemble mouse port
At the right of the case just below the floppy drive is the mouse port of the case. The vertical mounted PCB is the mouse logic, the horizontal mounted PCB is the electronic switch.

Mount hard disk
One of the first items that has to be mounted into the case is the hard disk. I hope that I never need to replace it because in that case I need to remove everything from the case before I could remove the hard disk.

Mount front connectors
A closer view to the PCB with the front connectors and the new switch (with the wire) to open the tray of the CDRW.

Mount floppy (1 of 2)
Now the floppy is fitted into the case.

Mount floppy (2 of 2)
It is difficult to screw the floppy (there is an extra hole for the screwdriver in the mounting plate for the CDRW).

Mount Ram
There is just no space left between the rear of the floppy and the ram.

Mount CDRW (2 of 3)
The AGP port is covered by the drive and only one of the PCI ports may be used if the card is not longer than the port.

Mount CDRW (3 of 3)
The (blue) wires of the small PCB of the power supply just fit between the power connector and the IDE-cable of the CDRW.
