What do you think about this equipment? And which version is better?
RAM 'doesn't matter', 4 GB would be plenty for normal router tasks.
SSD 'doesn't matter', the cheapest/ smallest thing you can get will do (even a USB stick/ sdhc card would, but a SSD increases reliability - I use a whopping 30 MB on my 30 GB SSD).
Depending on where you are, it might be beneficial to source SSD/ RAM locally, to stay below customs/ tax boundaries (but, well, in the grand scheme of things, a few bucks handling fee for your postal service won't change things massively either).
"8GB Ram 128GB NVMe" or "8GB Ram 256GB NVMe" (just 8 bucks more, so… why not) would be comfortable choices.
But this device doesn't really fit into this thread, as it's a new device for its full/ normal price (>130 EUR). This thread primarily deals with good deals (around ~50 EUR +/-) on decent used gear - the availability of new devices like the one you are looking at, defines the upper ceiling of what a 'good deal' could be for the used stuff we're talking about here. So probably better to start a new thread about these devices.
If it's like the one in your first post, with an RJ-45 jack labeled "Console", what you need is called a "cisco rj-45 console cable". Cisco made the standard for RJ-45 RS-232 ports, and the cables are almost always flat cable that is light blue or blue-green.
