Is there any need to ground every component to the case? Certainty I will ground the power supply with the attaching screws but do hard drives, motherboards and DVDs really need individual grounding or do attached cables accomplish this to a satisfactory degree?

The PSU is not grounded from the screws, the power grid accomplishes that. If you install all the components normally, don't touch it.

If your motherboard has contact to metal, it would most likely short out and explode (assuming it's touching multiple metal contacts on the mobo). Just install a PC normally like everyone else and you'll be fine.

No you do not need to ground anything otherthan the motherboard(which is completed when you attach the stand offs)

Actually standoffs prevent the metal of the case touching the mobo. There was a time where plastic standoffs were the standard for most OEMs.

Most high quality cases have brass standoffs and the shiny solder around the mounting holes does make a ground contact for the motherboard this also helps in shielding the motherboard from interferance.
Also the power supply does have an earth ground that is why it has a 3 prong plug.

I'm intrigued at the custom case part, is there a build log of the progress?
