Cheapo Bush one I've had for years. I bought it in argos for £4.99 when i needed a keyboard for my macbook as I had it on a tray out of reach. I mean to replace it but it works and i've never had any issues with it.
Whats the thing under the samsung monitor?
It's an audio interface. I do home recording of bass and guitar. Saffire pro usb. 2 mic/line inputs on it. I have some a pair of Behringer C2's and an Sm57 to record with. Mainly use it with my macbook but its good for managing audio on the PC too.
Yeah its handy means i can adjust game volume and mic volume without going through the setting in game i just turn a nob to what i like.
