Obsoletely Fabulous - case building basics

"Oh God. He's made of wood." ~ Leela

G43 + i7-4790 + wood case

I want to build a poor man's server case to hold four MSI G43 motherboard's and their accoutrements.

What don't I know....

Is the motherboard, power supply, or hard drives intended to seek grounding from their screw mounts?
Once outside of the box, figuratively speaking, can the power switch be eliminated by soldering the two wires of a normal switch together, leaving the power supply switch as the only on/off for a system that only turns off when the power goes out.
I intend on staining the wood to reduce micro-dust infiltration from the wood itself.

What concerns or whispering doubts leap to mind given this project. I've built computers, I've built boxes. Why can't I build a computer box?

  1. With terms of grounding, the power supply is the source of grounding for a computers components. No other components should be grounding at all (lots of issues arise when people get unintended grounding on the backside of motherboards with other case accessories etc. You could easily run a steel rail(s) with the mounting holes for the power supplies which is in turn grounded for additional static reduction.

    I would keep a power button integrated into your circuit design. I'm not sure of the specifics of the power switch, but as it isn't a locking pole type switch or however you want to phrase it, the 'on' state is only triggered by the brief closing of the circuit which is otherwise open. So your bridged power switch wires would be like holding your system power button in the entire time.

    My old roommate built a wood enclosure which had some positives and negatives when compared to a regular steel case.

    1. Screws and any additional fasteners are a pain in the butt since you must source longer equivalents for whatever components you want to use.

    2. Use acrylic sheets or something similar for your motherboard standoffs to be mounted into so you can have some sort of non-conductive tray-like system

    3. You'll need additional ventilation since wood is a fantastic insulator compared to sheet metal.
  2. You can and (IMO) you should - here's a bunch of images https://www.google.com/search?q=wood+pc+case&tbm=isch&tbo=u&source=univ&sa=X&ei=RWV6U5O_GsiIogTpwoKoAw&sqi=2&ved=0CCgQsAQ&biw=1483&bih=912 of wooden PC cases and many of those will link to build logs for how they did it
    Grounding of components is taken care of by the PSU so that shouldn't be a concern
    I'm not sure I understand your switch idea
  3. Your power switch answer is exactly correct, I knew I was overlooking something, Thanks. And insulation is not a problem as I am build from wood to create a quad of computers within a wind tunnel that will sit atop something akin to a 20" fan, that these 4 i7 systems which run 24/7 near full processes may do so unbothered by heat stress. And to the dusty allergens here, never been a problem. i first tape off my unused slots with no-lift bluetape then run all my computer cases open air, and they drop 20-40f for the pleasure. A good blow out once a year takes care of the dust. My 11yo, all-original, open air Pentium 4xp just completed a 101 day uptime. Cases are the worst things for computers. Let your processors run free!!!
