metal supports and ground

[Stoweboarder]

for my portable, i made a support for my relocated slot out of metal that is screwed into the sides of the board where there is metal coating and some screw holes, i was afraid that the supports might be touching a contact (even though they prob werent) and then I went so far as to wrap the metal pieces with electrical tape

will i have any problems so long as the metal supports arent touching any connections on the board?

also

for ground wires
on the ps1 screen there are two ground pin outs and thew one that is said to be used on the screen is 4, but i had trouble soldering to 4 so i switched to 8 which also says ground

does it matter what ground i solder too on the screen?

If it isn't touching any contacts, you should be fine. Also, ground is ground. I don't think it will matter what ground you use.

as a matter of fact, it doesn't. And if your metal support is touching ground and just ground, it doesn't matter either.
