Let's start off with one that needs no explanation. 。

Build by modder Thermal Mike and Thermaltake's U.S. team, they actually sourced for original DK arcade logos for this Donkey Kong case. 。

Looks like it paid off -- the mod definitely has that old arcade feel. 。

Taipei 101
。

What better way to represent Taiwan than with one of its famous icons?

The Supercarrier took around three months to build -- though if we're honest it looks like it took a lot longer.。

Just look at that attention to detail.。

The Wheel of Star, which is made by Modder Crow of Thailand, is by far the craziest thing we've seen. 。

We're told by a Cooler Master spokesperson that the PC case is fully functional, and equipped with a HDMI wireless transmitter, so it can still connect to devices -- despite being in that case.
