Excerpt: Today we're looking at the Gigabyte Aivia Osmium mechanical gaming keyboard, a fully backlit board that sports bold styling and looks to cater to discerning consumers who want something unique. The Gigabyte Osmium is not your average mechanical board. Are you looking for macro keys? Check. Is 6-Key Rollover not good enough for you? Ok, try 64-key NKRO on the Osmium. What about integrated USB 2.0? Nothing special there, so how about USB 3.0 here on the Osmium.
