homelab

I am currently looking into upgrading storage for my homelab. The two routes I am looking at are grabbing a dell r730 or a disk array. They are both about the same price, but my major purchase concern is heat and noise. My office/homelab is in a 10x10 foot room. I have worked hard to get the sound floor at my desk to be around 44dB, and the temps to top off at 79f, 74 on a good day with the door open. Is a disk array going to add more heat and noise to the room than a dell r730 server running proxmox with trunas?
