Oh yeah it def had the SAS Backplane wires, I'd switched to using the SATA on board since it doesn't have the same HD capacity limits. I think it was a max of 2tb with the backplane and I'm using a couple of 10tbs. Maybe their is some weird bios that requires it to be on board?
If I could find a internal server fan smaller then 20x20mm. I'd stick one next to my 1U CPU Cooler. But for some reason I can't find one. Needs to be smaller then 20x20 because it would sit on top of the motherboard in a closed 1U server rack frame.
