Here are some more photos of one I put together today and can sell. If you need more the LRS-350-12 is $28 on Amazon and the DC 2.5mm plug cables & light are only $4 and $7 each on aliexpress, I have the rest of the parts in stock.
With 2x miners and 3x voltage supplies I like to use a 12V RGB boat spotlight to take up the extra outlets. I do need to warn that the pretty lights attract cats like a moth to flame.
