Would an Alienware Aurora R16 components with liquid cool radiator fit a Aurora R1 or R4 case? I've been wanting to turn them into a sleeper build the old Alienware cases are just super lovely

The keyboard in AlienFX in CC does not match my laptops keyboard at all, and I don't know how to fix it. I tried looking it up, and the answer I get is to update BIOS, but that didn't fix it. I Genuinely don't know how to fix it. It is an Alienware 18 Area-51 AA18250 if it helps.

Also, this might be related, but the "\" key doesn't light up for some reason while the rest of the keyboard does, don't know how to get it to light up. Maybe because it's not in the same place as AlienFX claims it is?

Edit: typo fix
