love it man, one of my friends strung his pc across his room, it was funny as hell. then he made a pc case out of card board, it over heated and set it self on fire.
iv done weird stuff but i never built one with the guts hanging out. but i do have a really big tower that i managed to fit 5 micro-atx boards into which i turned into a linux cluster. it actully makes a pretty good rendering and compiling farm because two of the five in there are quads cores.
haha, I'de rather let it just sit on my desk with a rubber thing under it then a cardboard box that is most likely to ignite when playing a game under full load
it looks like you computer is wounded and its bleeding cables. Im not surprised if it does decently considering yyou said especially if u have a giant fan constantly blowing on it.
