Chosen Solution

I have this Mac Power Mac G5 and I cannot access the wiring for the desktop because that side does not have a side panel and I don’t know how to access it. It’s pretty much for the disassemble and cleaning of the product so I would like to know how to access the other side.

Unfortunately, you can’t. The other wall that is not removable by the latch because it is part of the “unibody” frame of the Mac.
