Any obvious upgrades from Wyse 5070 for low power applications?

As the title implies I'm looking to see if there are any obvious upgrades from the 5070.

I'm looking at switching over from Pihole to Technitium, and as long as I'm changing software I'm looking at if there is any real reason to consider changing out hardware. Currently having a hard time coming up with any hardware that provides any real benefit to me, but I'm always open to the idea that im missing something.

I currently keep 2 5070s running for failover protection and plan on doing the same with Technitium.

The only real requirements I have are low power consumption, being quiet (ideally fanless) and not absurdly expensive for the improved performance.

So, is there anything im missing hardware wise?
