At about 12:33, it looks like they're plugging expansion cards into a motherboard that still has power, as there's what appears to be an LED on on the motherboard. It's possible that this motherboard doesn't power the PCI slots in that state, but man, I would not be plugging any expansion cards into a motherboard without the PSU powered off.
It has been quite a while so I’m fuzzy on it, but I had a board with a status LED and it would stay on for a bit as the capacitors drained? Generally a good thing to watch when you wanted to properly pull power from it for whatever reason though, especially with how often I was thoroughly crashing it and then resetting things with my overclocks. :P
Yeah, I've had that too, but I don't think that that's likely what's going on there, if they fully shut the thing down, flipped the PSU switch off, and then started filming the card being inserted. LIke, it was maybe a couple of seconds at most. And honestly, I'd probably still want to avoid plugging stuff into a board while that is on, since I don't know what other stuff also might be powered up on the motherboard. :-/
