    Question Help with mounting PC case.

    Hi, I have a 2002 Subaru Liberty (they call it a Legacy in the U.S.). I am just about to try my first PC install in a car.

    I know a lot about computers but relatively nothing about installing equipment in locations not designed for it.

    I have an ATX desktop case and I want to mount it underneath my parcel tray in the boot. Iíll have to suspend it about an inch from the parcel tray because there is some items in this area that move when the boot is opened and closed.

    The parcel tray is not flat underneath. In fact no two points would be at the same level. Does anyone have any idea how I would do this?

    Thanks in advance for your help.

    You might try Expanding foam packing. just cut a cardboard box fo fit so the top is level. Put a piece of plywood in the box above the foam pack and let it expand and harden. This will give you nice shaped platform to mount the unit to.

    The foam I am talking about is available from most shipping supply companies.

    Check Foam to use as a base in fiberglassing, bondo work, etc. for more ideas

    Thanks for your help, that sounds like what i need. I just want to make sure I have this correct.

    Make a box out of cardboard and plywood about the size i need the mounting. Fill it with expanding foam and use a knife to shape the top half of the box to sit under the parcel tray.

    How strong is this foam? How would I mount it in the boot. Can I glue it the the underside of the parcel tray and then glue the case to the foam? How do I remove it when I sell the car?

    Or would I need to run some type of bolt through the case and foam into the parcel tray?

    I have used the two part foam and it will set up fairly strong. If, after it hardens, you dont thik it is strong enough, you can cover it with fiberglass layers to strengthen it. The plywood should be the part of the base you mount the PC to after you are done. The foam also will "glue" it's self the the wood as it sets. DO NOT LET IT EXPAND IN TO THE CAR. It will be impossible to remove. I would use heavy plastic sheeting to protect the car when you are letting it set up and form shape. then use bolts, screws, or some other type of fastening device to mout it to the car. This way you can remove it when you sell the car.

    Thanks, I think I know what to do. I'm going to start this weekend.

    A couple more questions - could I use the pc case rather than the plywood? Will the foam bond to the case? What kind of paint do I use the paint the foam? I only plain to paint it a matt black, Can I shape this foam with a knife?

    I'm going to try and stay away from the fiberglass, I don't have any experience in that area - I could really mess things up if I try that.

    I guess the foam doesn't need to be that strong if I run a bolt through the case and the foam and in to the parcel tray. Just strong enough to tighten the bolts so the computer doesn't wobble around in mid air.

    You can paint it or cover it with come type of cloth (felt). If you paint it I would use epoxy paint. I personally would see if I could match the carpet in the trunk(boot) and cover it to match. you can use some of the spray on adhesives to bond the carpet or cloth to the foam. 3M makes a good low odor spray adhesive.
    BTW here the foam I am talking about http://www.shopmaninc.com/foam.html
    THe spray on foam like you get from your local home improvement store will break down and will not last.

    Yes you can use a knife to cut the foam or a saw. I usually use a wire saw that campers carry. It makes quick work of the material.

    Thanks

    I can't thank you enough KB5WID for all your help. I'm ready to start, felt is a much better idea than paint. I'll put some pics and results back in this thread when it's all done.
