Any ERP like odoo can do this and with odoo you can even make maintenance reminders. Just remember they are business software so you have to look through that lens.

If you use ESXI as your hypervisor then you could use their virtual machine package to see if you like it. https://bitnami.com/stack/erpnext/virtual-machine

I do recommend manually installing it yourself if you end up liking it so you can understand how all the gears mesh together if you ever have to troubleshoot.

I’ve tried odoo and while I like it, a lot of the accounting side of things is lock behind a pay wall although there are third party plug ins that accomplish the same tasks.

Once I have more free time I’m going to test out Erpnext as it’s 100% open source with no pay walls if you self host it.

I’ve spent the last two weeks on getting a k3s cluster working and I’ve had nothing but problems but it has been a great catalysts for learning new tools like ansible and load balancers. I finally got the cluster working last night. If anyone else is having wierd issues with the cluster timing out ETCD needs fast storage. Moving my VMs from my spinning rust to a cheap SSD fixed all my problems.

The classic choice would be fractal design’s node 304 which fits six 3.5" drive in an ITX form factor. There’s also Silverstone’s CS381 which while being larger can fit eight hotswappable 3.5" drives and a micro atx motherboard.

Even if you go ITX you don’t have to feel limited by the lack of PCIe slots. Since m.2 uses the PCIe protocol it’s very easy to adapt it to your needs such as to an additional PCIe 4x slot. There are even m.2 10GBe cards in both intel and Realtek flavors.

Side question, what coral TPU do you have because it was my understanding that they use m.2, mini pcie, or USB and not the full size pcie slot?

I’d say replace your current server with a larger one that can pull double duty as a NAS and VM host. There are plenty of SFF nas cases on the market now.
