If there's a need for a switch between component and composite, I can make sure it's accessible by the back of the machine.
I'll have to give Super Cobra a try, to see if it works or not... maybe I just need to leave it at 1K, then... or another switch.
There's little or no drilling if you don't want to have any of the extras.
Regarding the power switch, I have my eye on some replacements, but I'm not 100% sure they'll fit well or not. Hopefully there's some options available to people here. Time will tell.
As far as switching the BIOS, pick one, then leave it.
For the reset/pause button combination, that sounds like an interesting idea to have short press equal pause and long press equal reset. Another option is to combine the reset switch with the power switch, and have a dedicated pause switch.
