I’m currently using a dell precision t7920, can hold up to ten 3.5 drives, has too many pcie slots, dual Xeon silver cpus. I had it running for about a year now, 24/7, in my living room, it’s in my rack now, and you can’t even tell it’s there. The poweredge series might be different when it comes to fan curves, but I can’t imagine it would be too different.
