rubber feet
When I was testing to determine if the Twinhan Starbox USB was overheating...
I pried open the top of the plastic case.
Didn't know about the screws at that time, and just assumed the case was snapped together.
I got it parted maybe 1/4 inch - just barely enough to slide a chipset fan in about half way.
Not a CPU fan - but one that goes on the motherboard chipset - very tiny.
I powered it externally, and noted that solved the temperature problem.
So, I knew that just minimal cooling would be sufficient.
My buddy and I came up with all sorts of overkill solutions for heatsinks, heatpipes, blowers, evaporators, plumbing, and liquid Nitrogen.
...Including, but not limited to cutting a hole in the existing plastic box.
As a test, he attached his naked board to a P3/Celeron heatsink meant for the Slot-1 CPUs (we have lots of old stuff around).
His heatsink and fan worked great!
My little chipset fan worked, too.
But, neither solution was elegant.
I just wanted to be done with it.
He wanted his to be a fancy conversation piece.
You see where it led us.
And actually, my box has 6 rubber feet on it.
In retrospect, I should have put more on the side, as I like to rotate the box 90 degrees to use it.
My box was way too big, until I realized there was room to put the power supply inside.
And, I
-so- hate those external wall-wart power supplies.
Nothing quite like using a stock power cable.
To each his own.
