foam case ?

[givingtnt]

so I have a project of making a computer inside a F-86F with the golden hawk colors.

I cannot afford a 1:30 model in plastic or metal. would be custom made and would cost like 3k$ to make.

so I decided to make my own. would foam be ok for heat and pc parts ? is there any danger using it ?

What kind of foam are you thinking? Obviously like styrofoam is going to melt, but you could use high density urethane, harder Polyurethane or Puren I suppose

high density home isolation hard foam.

the blue thick sheets ?  I expect the pc to get quite hot. because the ventilation is through the center of the aircraft (where the engin would be)

An F-86... Like the Sabre plane?

 

That would be interesting. I can't help you with your question at all but it would be neat.

Blue thick sheets is a tad vague But the home insulation foam is more what I had in mind with the polyurethane 

 

Although honestly you could just mount the computer to some plexiglass for heat resistance and better airflow and then make the model out of paper mache or another easier to mold material around the plexi

 

Polyurethane or other hard plastics would be pretty difficult to make into like a tubular shape for the hull of the aircraft imo

 

*Also, what do I waste my 1000th post on!?*

yes exacly

 

would looks like this but with a pc inside :

This video will give you a good idea. Shapable foam that you can cover in an epoxy to harden.

not at all. heat + carving + acetone and im all set for smooth lines

ooh nice. that will help with thermals of the case itself. 

 

cool !

I really like the idea of that

The foam and epoxy is whats used in RC Planes - http://static.rcgroups.net/forums/attachments/1/8/1/9/1/6/a3892933-227-Epoxy%20foam%20fuse%20011.jpg

There are a few 1:32 kits floating around the web if you know where to look.

Ik this doesn't answer your question regarding foam, but it's worth a look.

By blue thick sheets, I assume he means expanded/extruded polystyrene. It also commonly comes in pink sheets at the hardware stores for insulating houses.

 

The melting point is 240 degrees C, so theoretically you would be alright... I would buy a small piece of it, and set your motherboard directly on it while running some games or something, like a makeshift test bench just to see what would happen before going through all the work and finding out it will not work.

 

I would still play it safe and build compartments out of steel or aluminum sheet for the components, and inset them into the foam model. Long term direct contact with 80 degree C parts may have an effect on the foam even if it is still well below the melting point. Its really hard to know for sure without just giving it a try and seeing what will happen.

what about mounting the components to a board? foam is kinda nuts. and then i remember the static shocks i used to get off them.
