Ok, no point trying to hide it, I’m feeling pretty proud right now 
Today it was finally time to upgrade my farmer and install the new DIY Jbod.
Upgrading your farm starts with…taking everything apart
But when all put back together, It cleans everything up quite a bit
And just to demonstrate the sheer efficiency of SAS drive bays vs USB and SATA, this is what a single 12-bay replaces with only one SAS cable and one 8-pin for power.
Still have to make the second Jbod so I can shuck the last two USB dives, and then I’ll have space to add 10 more drives as well.
My biggest worry was temperature, but it turned out fine. All the drives are around 35-40C even with the dust filer in front of it. And total power draw at the wall is down by from 165 to 155W. Happy days
