CD Player In Pieces

Here we go.

All pieces removed from the chassis. No turning back now :)

The actual interior height is 67 mm. Also, the bottom plate is raised by 8 mm (to seat CD transport assembly on the plate). Even with 10 mm spacer to mount motherboard (which I/O rear panel is 44.45 mm tall) and FlexATX PSU (40.3 mm), the chassis is plenty tall enough for them.

Also, the depth of the chassis is deep enough so that the Mini-ITX motherboard (170 mm) and slim optical drive (126 mm), expecting less than 1 cm overlap. <sigh of relief/>

The front-panel PCB needs to be studied closely.
It hosts the VFD, IR Detector (remote control receiver), and 8 buttons. The dimension of the PCB will be measured precisely to produce the custom PCB for the PC front panel interface. The front panel buttons make contact with the tactile switches (5 mm tall, <<1 mm travel) on the PCB so when buttons are depressed the switches make contacts.
