Setup :
Framework Laptop 16 (the 7040 Series)
Vertical Mouse (~90 $) or Trackpad (~55-170 €)
I recommend a mouse (vertical)
Keyboard (~325 $ (with the build below))
or if you don't want to spend that kind of money and don't mind some soldering & 3D printing, you can make your own here (under 30€)
External SSD (~40 €)
Casing for External SSD (~35 €)
It's always better to have SSD as internals because windows will disconnect your external SSD (USB connected, yes even USB-C and Lightning) when you do large file transfers
Headphones (~77-150 €)
Comfy Office Chair with lumbar support (~170-450 €)
Standing Desk (~115-300 €)
ps: you can just get sturdy legs and then get a counter top from ikea
3D Printers (~350-1100 €)
