Hardware recommendation diy

[hYtas]

Hi,
I want to replace my UDM PRO due to crappy firmware and have been looking for hardware to use for a long time.

Since I would like to be future-proof on the road, I wanted to put something together myself.
I first had the IPU systems in mind but since I would like to have SFP+ slots, I discarded the idea again.

The OPNsense hardware I find quite expensive for 8GB RAM etc..

Since I still have space in the server rack, I wanted to use a short 2U server case. The server rack is currently located in the apartment, the router must not be too noisy. That's why I wanted to go to 2U and install a quiet cooling.
Hardware I had imagined the following for 1GBit PPPoE IPS and more:

CPU: i3/i5 10xxx or Ryzen 5/7
(m)ATX board
16 GB RAM
SSD
Intel 4x1GBit NIC + 2x1 GBit SFP
and free slots for more SFP+ cards

This should be more than enough for OPNsense and maybe 10GBit in future. Power saving would also not be bad (pay attention to my proxmox system).
_______________________________

For Proxmox I currently use the following system:

ASRock X300
Ryzen 5 4650G
64 GB RAM

10-15 watts consumption at 1-2% load for 8 LXC and 2 VMs. Therefore I would like to use Ryzen.

Does anyone have any tips on what hardware might be better? I would like to spend around $800€.

I got this and built it with 32 gigs of ram and a 1TB NVMe for less than $300 ... running ESXi with a couple of VMs already and its blazing fast.

Just take a good SFF workstation (HP Z, Lenovo P, etc..), Intel i340/i350-T4, Intel X520-DA2 second hand and new SSD.
Way more reliable, performant and cheaper than chinese misunderstandings with N5095/5105/6005... They will struggle with Suricata/Zenarmor/VPN to push some serious traffic...
