Oh, where to start.
the 52" tv next to my laptop?
the home made san?
The SARS project (in the 4u rackmount) ?
Oh, how about the carputer version 1 for the olds? (version 2 for the mr2 is going to be hot, keep an eye out for *that* thread later this summer)
(touchscreen for the carpc)
or perhaps something a little more oldschool?
or a-lot more oldschool (holy crap, that one is dated?!)
...or maybe you just want straight up off the wall?
this is a dual cpu (around when dual core stuff just was getting ready to come out, that was spiffy) watercooled unit in a 4u rackmount case, mounted on drawer rollers inside a desk that would survive a nuclear explosion. explanation not available, but I will tell you that it monitored the water temperature (yes, that 6" pvc pipe stores water for the unit) with a thermal diode through the joystick port.
...need I go on?
