Wooden Touchscreen Terminal - front

Wooden Touchscreen Terminal - front by barnoid.
This is a 15" LCD touchscreen with a Celeron 633MHz board with 128MB RAM in a wooden case of my construction. The case also contains the PSU. The bottom part of the screen surround hinges down to allow access to the monitor controls. The button mounted on the base is the power button and indicator light.

It has no hard drive and boots using PXE from my server, then mounts its filesystem over NFS. It runs Debian Linux, xorg, XFCE4, Metacity and Firefox. The button on the left of the panel at the bottom of the screen pops up a screen keyboard.

Currently I'm a bit concerned about the amount of heat that builds up from the PSU (reaches 75°C after a while), an external PSU might be required. Also it tends to run out of RAM when viewing stuff on google video (no swap, no hard drive).

Update: I've done some work on the insides, see here. It still looks the same on the outside.

Further update: I've switched from the above described software to running KDE. More details here

Overheating is expected. Wooden construction retains heat.
What kind of ventilation and airflow does it have?

See the back for the ventilation. The holes in the top are above the PSU. I'm trying to avoid noise and so the only fan is on the CPU cooler. Hence I'd rather use an external PSU than stick fans in, though it will need to provide enough power for both the motherboard and screen.

You'll need to stick in atleast one fan to have decent air circulation & thus bring the heat down. I don't see how you can do without it.

Wow, nice :)))
maybe you could try some VIA motherboards with C3 processors for lower temperature...

Not sure what make the screen is, I bought the insides from ebay. It used to be an information access terminal in a hospital. It came in a rather dull wall mountable plastic case. The touchscreen part is held to the front of the LCD with magnets around the edge. It connects to the PSU and to the serial port. It works with the 'fpit' X input device driver, which is also used for Fujitsu tablet PCs.

If you're running out of RAM and have a lot of linux experience, try out this; www.nfs-swap.dot-heine.de/

I use Network Block Device as swap on another disk free machine. It works quite well as long as the link stays up (if it goes down then stuff crashes), but it is quite slow. I'll probably just get some PC133 RAM off ebay or something.
