   Had to do that in ONE 18-port switch once. But ONLY once.

   Fortunately I tended to save caps from other old equipment
   so I actually had good replacements at hand.

   However I don't think the poster's probs arise from crappy
   little hardware issues.

   As for overheating ... I posted elsewhere about how easy it
   is to turn packaging material into a 'cooling box' for one
   or several little computers/drives/etc. Amazon has a huge
   selection of fans, many of which will operate off of a
   simple USB port - but you can always splice in an external
   wall-wart if you wanna save yer USB power.
