Looking for dual sfp+ router

Hardware Questions and Recommendations
1

Hi, I am currently looking to replace my Turris Omnia with a more powerful option for my main router/gateway.

I want two sfp+ port and ideally one 2.5GBE.

I have considered banana pi r4 pro but seems overpriced. I have considered Ubiquiti UCG Fiber but would prefer remaining Open Source. Specialized mini-pc looks overpriced as soon as you start including RAM and storage.

For now the best value seems to be Lenovo m720q 150-250€ (depending of the RAM amount) but will need to find pcie riser and right card.

Any other option to consider?

I live in France if that matters.

Dell Edge 620/640/680 got two SFP+'s but no 2.5GbE.

8/128 in the 620, 32/256 in the other two.

Might be tricky to find in EU though.

I can only find some listings for 620 at 400€+ within EU and nothing local on my usual marketplace

I know a place where they sell used 640s at ~200, but I'm not sure it's OK to post.
PM me if you want the link.

You can easily find original and oem risers on Amazon and AliExpress.

(just a couple examples I can't vouch for that specific models).
There are original backplates for quad gigabit cards like Intel i350 but for SFP you would need a 3d printed one which there are many models:

As for the card a Supermicro AOC-STGN-I2S fits well enough inside the case:

It's about 30€ "new" from eBay

Not sure how it will work as a router if you need a sfp onu module...
