I was mainly looking for used ones like Optiplex, Thinkcenter etc when I made this. Hence those brand filters. Thought they were a much better deal than a beelink, so I guess the site is optimized for that. Oh also can you send the link for the KingHive Pro listing? Might be able to filter out brands like that.
There's a free shipping filter, but if you're not in that country, shipping costs a lot. The solution to that is to add more marketplaces, which I'm going to next. Where are you located?
