hello :)

hope i got the right section here...

do any of the components inside of the pc use the case chassis as a 'common ground/earth' ?

im asking because i just built a new desk for my home studio, and im wanting to incorperate my pc's (minus their cases) into the legs of my desk...



when ive built pc's in the past, i see that every component or there abouts is screwed onto the metal pc chassis in one way or other.... the mobo, psu, pci/pci-e cards etc... which leads me to believe that its been done like that for a reason.

is as it first seems... a 'common ground/earth' ? or is it maybe a sencondary layer of protection for your components in case of accidential earthing / getting rid of static charges / or failure of primary earth circuit ?

would it be wise to strip out my pc cases... and incorperate the metal mobo mounting plate and pci card fixing plate into my design ?

if anyone has any other useful advice that would assist me in my little project... id appreciate it if you would be kind enough to share it with me :)

many thanks in advance :)
 
i would reccommend putting it at least on a proper motherboard tray

look at a few test benches maybe and adapt their layout to fit your space requirements?
 
As mentioned, use a motherboard tray, this will keep the cards and backplate at the correct height and orientation. You can trim the backplate down naturally, and it will also ground all the parts. Means the static will not build up. Make sure you ground the psu to the tray.
