you like Mecha and Mech-design

I prefer mech design. As in I like to look at moving mechanical components, engines, tranmissions, gearing systems, it always put a smile on my face. Mecha (assuming robots and stuff) is cool. The Warhammer Dreadnought and the Matrix APU are the ultimate cool, but it can get kinda weird when a machine weighing 1000 tonnes can jump around and move like a human ( Code Geass Mechas).

I'm not too familiar with Mechas in the way you meant it so if I misinterpreted your question let me know.
