So I recently bought a cheap Rift 1 to try out VR. I like it, but always moving my PC to the next room (for 4x4m Roomscale) is rather annoying. So I thought about "upgrading" to a Quest 2, drilling a hole through the wall and getting an 15m active USB-Cabel for 50€ for the PCVR link thingy. 

Do these longer active cables work with VR/Quest2? Are there any differences with thse Quest 2 versions (besides 64/128/256GB)? Some sellers try to advertise "newer 3rd Gen from 2022". I'm asking since I could get a used 64GB one with the Kiwi Elite Strap for roughly 300€ or a new 2022 128GB one for 380€ + extra for the elite strap.
