Need tips for future owner of Rog ally X

Hi,

i juste bought a second hand Rog Ally X, first i would ask what are you advice to check when i will receive it, it seems in excellent state but anyway i would avoid any trouble later.

Second, do you have any tips for installation, like install G-HELPER or not, uninstall armoury crate or not? That kind of things and link to tutos if you have btw.

Thanks a lot, happy to in Rog Ally x's team ! :)
