    computer into wood enclosure

    i am making a fake floor type setup in my 4runner, it will be a carpeted (on the outside) wood enclosure

    i bought a case for 30 bucks and its too big (for my desires). i have a matx form factor and was wondering can i just screw the mobo into the wood enclosure (using the standoffs of course)

    someone mentioned something about grounding the circuits? i guess that means mobo and PS? how do i do that?

    fire? is that a concern?

    you could jsut screw standoffs into the wood but most mobos are earthed through the metal around the holes intot he case so you just need to have all these points linked and earthed. Might be easier to get an old back panel off a case (the bit the mobo bolts to) and screw this down 1st. If you hack up a case you can get the pci card supporting bit too.

    EDIT: jsut gonna make myself a bit clearer:
    If you have an old case with the side the mobo and the back face were all the cards bolt to and the back conencters come through just cut this (carefully as the thins steel is sharp) and bolt this down. This way you get the nice earthing (make sure the case section is then earthed to a common point along with other parts of your system) and you get good support for any PCI cards - if you have any. Loose PCI cards will cause you a lot of trouble with hanging and crashing. YOu might also want to brace the L shape as if it flexes even slightly then the cards will twist out. Thats why cheap cases are crap and cause loads of trouble.

    .

    Use standard standoffs you should be fine.... wood is actually great to use because it doesnt conduct electricity !

    This is interesting, i heard that the mobo is grounded via the psu connection

    well yeah it is for the current flow but the PSU is also metal (and therefore must be earthed due to regulations) and bolted to the metal frame to which the mobo is bolted too using metal standoffs with metal rings on the board where the screws go. Some mobos have fibre washers and plastic screws but i have never used one of them. I was concerned about the direct electrical connection to the case when i built my 1st PC but i guess it makes sense to have it earthed.

    I don't have an enclosure...I hauled out my glovebox compartment...and made a new glovebox lid from MDF...the mobo and the ITPS are mounted onto standoffs...I have no problems in that area....

    Yeah i was jsut gonna add, try it with no earthing, just using the wood as it will be easy and see how it goes. If you get any problems try earthing it. I would still make provision for decent PCI card support though.

    I don't know if this is correct or not...but my mobo isn't grounded...well at least not at the standoffs...I assumed it should be isolated....but i have been wroing before....

    Yeah it could be, i have seen some isolted ones but never built one. The metal rings ont he mobo might not link to anything and might just be there to protect the GRP board from damage fromt he heads of the screws. At the end of the day if your mobo is normally bolted to the case using metal screws and standoffs then it isnt going to do any harm bolting it to metal again. But if it isolated then keep it so. I always assumed the earthing was to protect the board from static. Like the way i always have a PSU plugged into the mains at hand when working with electrical stuff to earth myself.
