    This part is not quite true:
    "If you have ever felt aluminum it stays cooler than the ambient temp."

    It may "feel" cooler, that effect is due to the Aluminum being able to dissipate heat better than the air at the same temp.

    Water has a similar effect.

    Direct measurement of an AL object sitting on a table for some amount of time will show the same temp for the table, AL object and the air in the room.

    But the object and the table may feel like different temperatures.

    AL is certainly an effective heat sink material, which seems the point of the post and very accurate

    Even very slight movement of air cools aluminum. I swear, I just let this chassis sit for 15 minutes on a bed in 68 degree temps. Feeling this chassis right now its easily 20 degrees cooler than the ambient temp. I should have a few PC heat sensors laying around, I want to hook them up to the chassis and see if this is really true because its kinda errie how it just stays cold, I just set it on my lap so I could type and I could feel the coldness through my pant leg. Here are some pics of a custom build for diosagain that is the first chassis to use the shelf system. This is a custom DIN 1.5 setup. The renders at the top of the post are the DIN 2.0 setup.

    I should also add that this chassis is extremely lightweight, yet extremely rigid due to the fasteners and bends.

    Let me know how the temp measurements turn out
    do the same test with the case and a glass of water on the same table.

    Ambient is ambient.... let it sit long enough the air, table, case and glass will all be the same temp.... it is a branch of physics called thermodynamics.

    The case looks great! I can't wait to get my hands on it.

    i may be interested in one.

    i dont know how much room i'm going to have because i molded my screen to my 03 mustang double din bezelradio bezel.


    does the screen mount to the chassis?

    I am working on a piece of .063" aluminum that is cut to match a 7" touch and LCD and also match up to the mounting holes on the chassis. I believe a lot of trim applications will not be flat however. This is where the aftermarket or custom trim comes into play. I have 15lb HDU (high density urethane) that I can route. That would be perfect for mounting and LCD and conforming to auto interior lines. It already has texture naturally and would look nice painted and would only be supporting the weight of the LCD and touch panel. But yes the best idea would be to have the screen's trim mounted to the chassis using the same bolt pattern.

    Hello, new to these boards!

    I will definitely buy this if you finish them...

    I just have one question:
    Is the center "shelf" removable?

    Yes the center shelf is removable. It needs to be for hardware mounting purposes. Here are the latest renders of the adjustable design. You can basically mount the 'L' bracket plate at any angle, top bottom, whatever to suit your vehicle mounting angles. I took my time on these renders, enjoy:

    Do you think I can use this as a "case" to mount a computer into? Without using an LCD. I want to use an 8" lcd, with a custom dash. If this could be a solution to hiding the computer away...it'd be amazing.

    Thats what this basically is, a case. Its made for holding all the PCB's of your autoPC together in a grounded, protected, and lightweight enclosure. As long as you mount this chassis behind the LCD you are fine. Just make sure the LCD ribbon wire is long enough. You can extend the backlight wires if necessary.
