Here, the CD-ROM is screwed on. After some thinking, I found out that a standard power supply (not shown) shall be mounted besides it.

An early test fit inside the case.

Notice the transparent plastic tube down to the right. It lets me push a card-mounted switch from the outside of the case. The switch is the one that controls the CRTs signal source. By that, I mean whether the tiny, internal screen will show Linux or Discovery Channel. The white cable on the picture will be the antenna input for the TV.

Mounting the power supply:

The image shows the same old bracket as shown before, this time with a power supply on it. I guess the warranty is voided now, because I had to drill a hole in it (not shown) to screw it on to the frame.

The TV Cable

While waiting for the order-by mail- computer parts, I have managed to mount the antenna input. I am very pleased with this. You do remember the transparent plastic tube that switches between TV and Linux? The TV-signal will come through this cable.

The tiny aluminium bracket that fixes the coax to the frame is actually leftovers from the SCSI CD-ROM drive. I have recycled almost everything from it. The coax plug is fixed to it using the same two screws that mount the cable itself to the plug. The TV plug is available through a hole that I drilled in the backplate. Isn’t it a beauty? Back view…

Completion

I have now received all the parts Luckily, they seem to fit inside the case with lots of clearance. Here is a picture of all the parts mounted inside, including the main board. The computer is actually installing Windows XP when the picture is taken. My old Mandrake Linux 9.1 unfortunately did not seem to have drivers for the built-in graphics. Therefore, I will have to use Windows and Knoppix until I download a newer Mandrake-version.

Now, it is time to mount the original backplate. Caused by the extremely deep picture tube the TV originally had, there is a box on the backside. None of the parts in my project needet this extra space, so I cut it of.

The hole was filled by a piece of hard plastic. From where, you ask? My old SCSI CD-ROM. That old junk really proved useful.

I cut out holes for the connectors on the motherboard, and a hole that the cables will pas through. As you know, the cables for my internal keyboard, CRT and audio amplifier need to be plugged into the motherboard,
and the cables must come from inside.

The backplate used to be gray, but it looked ugly. Therefore, I coloured it with a dried-out, black permanent marker. When I buy a new marker, the backplate will be completely dark.
