I chose this motherboard because it was compact, Had 2 x SATA3 connectors, 4 Sata2 connectors and a PCIe8 and a PCIe4 slot.
I use the sata3 connectors for the Parity and the cache drives.
Currently it runs 8 x 2tb green drives and can hold up to 12 drives.
I’ve only just installed the Hotswap bays. It ran for about a month on the 6 internal drives without errors.
I have 2 spare ports on the adaptec controllers, so I might increase the capacity to 14 drives if I can find a suitable bracket to hold the drives. I’ll worry about that if I ever need them.
I removed the top fan in the case, to reduce noise. (Not needed) The front and back fans produce adequate air flow.
The case has rubber mounted brackets for the drives, so it runs very quiet.
I like this case because it allows the cabling to enter from the back, which makes the front look quite neat.
I mounted a USB header inside the case to get the Flash drive out of the way. I had to file a little bit off the bracket so that it fitted neatly between the backplane screws and used these screws to clamp the header down.
I know I don’t need 4gb of ram but that was the smallest amount I could buy. Wasn’t very expensive.
Possibly socket 1155 and i3 are also overkill, but I wanted to build the machine using current technology.
Even so, the cost per gigabyte of data is much lower and faster compared to an off the shelf NAS device.
I haven’t done the power figures etc yet, but I don’t think it will use much. The processor is rated at 65W when flat out and the green drives are low power users.
