Nice job.I want to buy the Quantum boards from HLG but dang there not cheap when you go to alibaba get a board for 20.00 but I didn't trust buying from there .I googled them and some bad reviews ,I really would love to buy for there i could do 8 boards with heatsink drivers shipping around 400.00 450.00 but I didn't want to throw my money away either .Anyone ever buy from alibaba.
