I mounted my motherboard directly on the plywood bottom, and the hard drive next to it.

In the picture below the plunger is at the bottom left, the two front satellite speakers are the black pieces to the right next to it. The hard drive is above the lower satellite speaker. The big black box at the right is the subwoofer. To the top left of the subwoofer is the PSU. It is placed high up so that the fan drives the hot air back behind the subwoofer.

Here's a side view:

The wooden crossbar serves as a support for the playfield monitor electronics box, which did not stay attached to the monitor itself after I decased it. It also supports the distance sensor aimed at the plunger.

The 15" DMD monitor was installed in portrait orientation behind the subwoofer. Lots of cables!
