I don't have a specific site or store that I look at. I'll be buying from a random retail store in my country. My other 2 choices were:
https://www.gigabyte.com/gr/Chassis/GB-C200G#kf
https://en.sharkoon.com/product/TG5#specs
I also looked into the NZXT H500i, but I won't be watercooling, and I've heard it's really good only if you are.
EDIT: Forgot to mention: the reason that I'm really looking into the Sharkoon cases (besides that I have Sharkoon mech keyboard/mouse/headset and I'm really satisfied with them, so I trust the company overall), are because they include the RGB fans, so it saves quite a few bucks, if you think that each fan costs around 15-20 bucks, while most cases (like the Gigabyte above), would require me to buy at least 4, which would cost almost 60-70 bucks extra which I could invest elsewhere.
