Your better off going a gaming keyboard if your building a gaming system. I use to own the Logitech G-15, it was great with illuminating keys, LCD displaying player stats, but I changed to the Z-board. The Z-board would be IMO the best gaming board out there as you can detach the keys and place different keys (frag) onto the board. You can buy different frags for different games, i use the battlefield 2142 frag for when i play the game. It gives you a massive significance in game play. Heres a link
