I found something on an old backup CD...
What you see here
looks inconspicuous enough
... and can actually be opened.. but what might that be
Well...There's fans on the backside
And some sort of box on the inside...You might have guessed it.. (Click to show)
It is (or rather was) a TEC powered mini fridge
Back in the days I got fed up with lukewarm coke on lan parties and decided to do something about it. A 1L bottle of coke fit inside, maybe even 1.5L. Finding a PSU that could dish out the additional amps on the 12V rail for the TEC was kind of a challenge back in 2001. I think it ended up with a 550W server unit or something.
The TEC was sandwiched between two enormous heatsinks and cooled via 2 Papst high powered fans. The small holes on the sides are actually for the air exhaust. It was switchable by the flip switch on the front panel and sounded like a jet engine. The tiny fan inside is for moving the cold air around thereby optimizing the cooling performance.
Water condensation on the cold plate was sky high but some tissue laid out in the back of the case fixed that nicely.
Ah I liked that little contraption
