"[...] host Nextclound [sic] and a couple apps"

So, what are these "couple apps"? You already have a decent storage solution. You might consider a RPi 4 with 4G RAM for NextCloud and some apps.

Other than that, I personally like the ASRock DeskMini A300. Slap an Athlon in it, and call it a day (keep in mind you need a "G"-Processor, with iGPU!).

At home, I've built a homeserver around a X470 and Ryzen 5 2600 - it runs everything using Unraid: Storage, Home-Assistant, PLEX, Node-RED, Grafana for the living room display, the secondary pi-hole instance, and also my personal Gaming VM. It runs at 15% load during idle, drawing 70 W (including Vega 56 GPU).

I'm pretty happy with my setup.
