I've gone through dozens of gaming keyboards during my decades of PC gaming, from generic off-white Wal-Mart specials to elaborate, fully-programmable, back-lit monstrosities. The Cyborg S.T.R.I.K.E. 7 from Mad Catz is the first gaming keyboard I've had to screw together before using.
For the $300 asking price, one would think things like using a tiny screwdriver to connect all the bits together would have been handled by the manufacturer, but the S.T.R.I.K.E. 7 is a special sort of keyboard. Completely modular, its various sections are held together by screws and pieces of wire.
