|I've never heard of a keyboard referred to as 'mechanical'. Does it have gears and pulleys inside? If that's a mechanical keyboard, what's a non-mechanical keyboard?|
The pc.mmgn.com link you refer to mentions the adapter Jolicloud linked to so assuming you already knew you needed it, is there some other problem you're anticipating?
Kind of a coincidence both you and the fellow in your link have the asus p8p67 motherboard and that obscure keyboard.
