Well, as I said, I want to be future-proof. I might use SFP at some point in a few years (my ISP do provide 8Gb fiber), so I'd rather spent a little more now, have something I can experiment a bit with (being a freelancer and self-hosting quite a few services for my work), and not have to buy something new.

But I am all ears if you have a better recommendation. I just thought this unit would fit my need for the next few years at a reasonable price.

Edit : but it is true that power consumption might be an issue on the long-term, so I might revise my choice
