I love a PC case with a bit of nonsense. Yeah, sure, gimme an extra screen or make it out of wood. Tiny and flavoured coloured like matcha? Yes please. That's why Amiiba and its new Ferra case appeals to me so much.
Its dinky case has a big, round circle on the top of the front panel with a pulsing black liquid—a ferrofluid— and it comes with a magnet to mess with it. Not only that, but a microphone built into the back of it means that the Venom-like blob can also react to sound.
