In my homebrew 3kV power supply, I used a high density polyethylene cutting
board I bought in WalMart's kitchen department for a couple dollars. Works fine,
but I don't know about it's temp rating. In my design, I used a fan to cool
things down and I placed the capacitor bank right in the outflow of the fan, so
temp is not a problem. Be careful if you place it somewhere else.
