I used to run a Dell R710, but that got expensive with the electricity prices shooting up. So I moved to a standard consumer hardware PC in a rack mount case. Ryzen 5 5600, 64GB RAM, 500GB NVME, SSD boot disk, 6x 3.5" disks for storage. It uses half the power and is a fair bit quicker than the old dell with dual X5670 Xeons. One day I'll move to just 2x larger disks instead of 6, but that's expensive at the moment.
I totally get moving away from the dell. I've got one sitting in my rack now, and I've been thinking about getting a nuc or two as replacement to see if I can drop my power bill.
How much of a difference did you notice in your bill when downsizing?
It's running at roughly half the power of the dell, which was at 220W idle. A lot of that will be the spinning disks, HBA card and 4 port intel NIC. A barebones system with just one ssd would be about 30W idle.
The NUCs are great but storage and networking are limited. I use Opnsense in a VM as my router so needed a few more ports. And the storage options on a NUC seem very limiting. Perfect for application servers, just not storage servers.
That's about what I was expecting. Yours is running about 30W higher than mine, but that's still a hell of a delta.
Thanks for the other points as well! NIC quantity will be an issue since I will be moving my esx over, but hopefully I can limp by on a single line and let VLAN tagging handle most of my mess. I've been running some of my VMs via iscsi storage, and it performs well enough for my uses at home.
