yeah but it's bad because it can catch fire, why alluminium can not, to be honest i did not have any electricity problem with aluminium, if you insulate well there is not this issue, just use plastic for stand offs motherboard
Regarding the flammability of wood I found an interesting read below(page 8 to be precise)
https://www.fpl.fs.fed.us/documnts/fplgtr/fplgtr190/chapter_18.pdfI believe even even prolonged exposure in the mining rig will bring the temperature above 100C so I think its safe to say it wont catch fire.
