Upgrade your original 1984 Macintosh to run OS X Snow Leopard.

Step 9 Boosting the ventilation.

The original Macintosh was passively cooled. Meaning it had no fans, however my upgrades might not quite manage without a fan.

The original macintosh has two rows of vents on either side, and two vents at the top. It made sense to mount a fan to draw air through the bottom, and expel it out through the top.

I had already got a sturdy frame with the motherboard mount and original metal mount. 

Using some more styrene I was able to create a large L shaped section that would create a second 'roof' inside of the machine.

Before gluing the two sections together I cut a large hole to mount the fan onto, and a gap to fit around the I/O ports on the motherboard. I used superglue to hold the two sections together, then epoxy resin to strengthen the joint.

This section sits, into the frame, and is held in place just with a few squares of styrene for it to clip under. This makes it very easy to get in and upgrade and fix the internals.

At this point I thought it would be best to check everything still fitted.
To my great excitement it did!

You can buy small plastic compasses with a cutting blade (plus spares). They are in most UK hardware stores. You can then drill a tiny pilot hole and scribe both sides, flex the styrene sheet and the circle will eventually pop out in one go, even in 3mm thick sheet.

 It is the original Macintosh. In 1984 they released the Original Macintosh, followed closely by an version with upgraded RAM (my model).

There were many Apple computers before the Macintosh though!

Glad you like the project, be sure to vote.
