Hello!
I'm super new to mech keyboards, don't really have much money, so I decided to get a cheap old mech. Cleaned it, fixed some screws, but the problem is, it has a 5pin connector. I read a bit about the adapters, and found out there are passive and active ones. No idea which one I should chose.

Sorry if this is in a wrong section, my first post here.

From your pictures, unless someone knows exactly what keyboard that is (which they well might—I'm not exactly the most knowledgeable on Alps stuff), we can't really answer your question. A picture of the bottom of the case, especially of any switches or labels, could be helpful.

There are two common protocols that used that same connector: XT and AT. The XT protocol needs an active adapter to use on modern computers, while AT can be passively adapted to PS/2. If you want to use the keyboard with USB, you'll need an active adapter either way.

I will edit this post with some pictures of the bottom.

Wow, that's a pretty generic label.

It has lock lights, so if I had to guess, I'd say it's probably an AT keyboard. Some XT keyboards did have lock lights though, so that alone isn't a perfect indicator.

Yep super generic, any way I can somehow get more info about it from the inside? Or maybe posting in Indentify keyboard will be better?

Assuming it's AT protocol, you only need a passive converter to get to PS/2. Something like this will do: https://www.amazon.com/dp/B0016RTO1M

If you need to ultimately end up with USB, I've had good luck with these "blue cube" active adapters. https://www.amazon.com/dp/B000BSJFJS
