Any idea if this is legitimate? It seems too cheap to be true.

Found this where there's a listing for ASRock B150M motherboards for 45.36 USD and they supposedly have over 1000 of them. If this is real, that is quite tempting.

Probably a company who buys stuff by the pallet, usually paid by weight, and then refurbs them or sell them as parts.

$45 sounds about right for a reused part.
