NewEgg has a bunch of nonames for $7-12 which appear to be identical to the ones in my lab, which also have no identifying marks. Separate AC-DC power supply brick going to a switch and a 4-pin Molex, separate Molex-SATA power converter, and a small black box that takes USB on one side and has a SATA port and 3.5/2.5 PATA on the edges.
