Solid TKL board

Hi, looking to replace my ~13yo Filco Majestouch 2 for a tenkeyless board, and i want one that feels just as solid, so topmount with a steel plate seems to be the correct choice. I have no idea what to look for as keyboards changed a lot since i bought it.

I wanted to just solder hotswap sockets into the old Filco but i want media keys and the bottom casing screw mount is broken in the middle and the entire board is bent inwards (smashed it with my fist a couple times when playing DotA in the past).

Budget is around €500 all in, ill be using PBTfans keycaps and Gateron Melodic & Boba U4T switches. Ideally it should come in black and be in stock in the EU
