Pros: Mechanical, MX Brown switches, LED backlight on WASD keys, media keys, full NKRO over USB, Overclock.net edition
Cons: Doesn't ship with a USB to PS/2 adapter
First off, it's Overclock.net edition! Although mine misses the keycap with the ocn flame, it's still great with the full ocn logo on the spacebar.
It's mechanical. I need not say much about it.
MX Browns. Feels great. Almost no sound, and isn't a bit hard to press. My typing speed has increased a lot than on the cheap membrane keyboard I had before. Feels great while gaming too.
Has full NKRO over usb which has to be turned on by a DIPswitch underneath the board. With that turned off, it has 6kro.
LED on lock keys as well as the WASD keys, and the ones in the latter can be turned on/off. Although I don't need it, but doesn't look bad.
There are media keys to control pretty much everything about music, comes in handy for me.
The Win key can be turned off while gaming, and the Ctrl and Caps lock and Alt and Win keys can be swapped with each other, both via the Dipswitch underneath. The former is quite useful for me.
The board comes with red WASD keycaps and a keycap pulling tool, and a detachable USB cable. Although it shows a USB to PS/2 converter in the user manual, it didn't ship with any.
