Yes, the consensus (offline) had seemed to be that humidy, thermal insulation,
etc are not issues; and the only issue would be flammability. And yeah, I
actually watched a capacitor explode under ideal circumstances (it was shadowed
dark behind the box where I was looking, wondering why the prototype game box
was behaving badly); it shot a beautiful little jet of flame.<br>
<br>
Incidentally, Sebastian Hyde has pictures of a really beautiful black walnut
PC. I think the right word is "baroque". Really beautiful. But yeah
consideration would have to made for the fire issue.<br>

I had noticed that the Helmer thing<br>
("bewwulf in an Ikea cabinet") is not<br>
really in a wood cabinet (the steel box can be put inside a cabinet). I'm<br>
assuming it's unreasonable to actually make a wood cabinet? On account of<br>
humidy, or just weight? To me it just sounds easy to build a wooden rack for<br>
a bunch of ATX motherboards. And it could look nice. Thermal and electrical<br>
insulation would be OK, and humidy controlled with a good paint job on the<br>
interior...?<o:p></o:p></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>What about fire? Anything
electrical can in a worst case pop hot/molten<br>
metal before frying and/or blowing a breaker. Capacitors blow up<br>
(literally). A wire is badly soldered and pulls free and grounds out,<br>
spattering white hot metal.<br>
<br>
Inside a metal shell, odds are you won't get a REAL fire as there isn't<br>
much actively flammable around. In a wooden box, carefully dried by six<br>
months of 50C heat... it wouldn't take a lot to get real flames,<br>
especially if the box had e.g. a cooling fan mounted to actively fan a<br>
hot coal into flames.<br>
