I’d deduct points for Hardware Customizability if the Switch PCB Socket uses a Non-Customizable Design. Although the Ducky One 3, NZXT Function, and Wooting two HE score the exact same in Hardware Customizability, the Ducky One 3 and NZXT Function use 5-pin Kailh “universal” hotswap sockets, while the Wooting’s aren’t customizable, and I think because of this the Wooting should have some points deducted from there.
There are also 3-pin Outemu hotswap sockets you can find on some cheaper boards (like the K552) that definitely limit customization since only Epomaker/Akko and Outemu switches can fit in there due to the sockets only supporting 3-pin switches with thinner pins (at least from my knowledge. Kudos for Epomaker/Akko for making custom switches that fit in Outemu sockets) and switches in these sockets are more difficult to take out than switches in Kailh sockets, but you can still fit other switches in Outemu only sockets (there are lots of YT videos showing how).
Also I think that the ease of opening the keyboard up (like taking it apart) should play a part in Hardware Customizability due to some people liking to apply mods to keyboards like taping the back of the PCB with painters tape or filling their keyboards with foam or other materials to dampen the sound. For example, a keyboard having glued/soldered wires (NZXT Function), hidden screws (TKL + I think Full Size Ducky One 3), or a structure that makes it really hard to take apart without possibly breaking the keyboard (ASUS ROG Strix Flare II Animate from a YT review I’ve seen) should deduct some points from Ease of Opening.
I’d just add two more weights in Hardware Customizability called “Switch PCB Socket” and “Ease of Disassembly”. For “Switch PCB Socket”, I’d have 5-pin Kailh or Mill Max (somehow) sockets be a 10, 3-pin Kailh or Mill Max (somehow) a 9.0, Outemu sockets a 7.0, Non-customizable sockets like Wooting ones a 5.0, and soldered or membrane dome a 0, and I’d have “Ease of Disassembly” be subjectively assigned (I’d only recommend doing the Ease of Disassembly test on mechanical keyboards, and if it feels like it’s difficult to take apart, give up or find some other hidden screws before opening it up).
Overall for people looking to buy keyboards and mod the crap out of it, this is a huge improvement but there are still a few things I’d like to add.
