And technical lego offers great ventilation options. Not so hot on EMI though.

Maybe it isn't UV alone, but acrylic (e.g. Perspex (TM)) does discolour and become brittle after long exposure to sunlight.

Is that the one that leaves the white deposit on the surface?
Should that not be flu - orescent (hyphen for pronunciation purposes only)?

Reading these comments on DIY Laptop Cases, I am remembering from somewhere in the distant past a kit for making a tool box. I can't recall whether I saw this at an exhibition, or read of it in a magazine.
There was a sheet of metal, probably dural about 10 gauge or 1/16th inch, there was a length of channel, 'L' shaped but curved rather sharp angle. This must have been twice the thickness of the sheet and had a grove milled along each edge. Cut 4 pieces of the length of the sides of the sheet, slot the short side of the angle on to the sheet, the corners are then open, they weren't mitred, but I think a separate preformed corner was fitted. This was one half of the box. Do the same for the other half, fit pieces of sheet metal in the groves of the long side of this bottom part to make a deep box. I can't remember the details of fitting hinges or fasteners.
Does it ring any bells with anyone, or is there any place one search for information? I presume it couldn't have been very successful otherwise they would still be around.

I Saw a nice alloy box about the size of a laptop in Makro containing a game call Magnetrix. About 10X15x4". It had a cut out lid for your screen! About £25 including the game!

In which case you mean 16 gauge. Incidentally dural has to be heat treated if you wish to bend it. I used to look after a salt bath heat treatment setup during the war. Twenty minutes in molten salt at 490/500 C followed by a water quench. After 2 hours, dural re-crystallises and has to be heat treated again for further bending. We called it 'normalising' but more correctly it was 'solution treatment'.
O.T. I know, but it brings back so many memories!

Sounds like the Vero kit I mentioned in a previous posting.

If you try to market it, Lego will go after you.

Whatever happened to those black, vac-formed briefcases which were all the rage years ago? They were available in several thicknesses. I still have one tricked-out as an control interface for the BBCb. (jpeg available.)

Thanks to everyone for your suggestions. I am currently half way through my proto-type case and trying to squeeze everything in!

What did you decide to use in the end? Wood? Metal? Lego?

Why? It might be a problem if you without permission displayed the Lego logo on a laptop that you sell, but just using Lego as a buidling material should be O.K. It is not as if you compete with them. On the contrary, you buy and use a lot of their bricks for building these things. Just don't market it as "The Lego computer".

If there is anyone else intending to embark on a similar project, the "memorable gifts" catalogues that arrive on the doormat at this time of year sometimes have cases in a variety of guises. I saw some this weekend fitted as CD carriers.

I might add, by the way, I have not yet indicated what it is I am squeezing into my case.
