Odpovím si sám - může to někoho zajimat - uvnitř jsou střeva z Great Wall PSU a Great Wall je odpad - jak někdo již napsal na tomshardware.co.uk:
They're called Great Wall because they were used at the Chinese borders to repel the mongols and other unsuspecting warriors. That's why people wrongfully say the Chinese invented the gunpowder, actually the explosions that routed the invaders were the Chinese PSUs hence the name "Great Wall".
LE: I'm suspecting that the Chinese nuclear program is also based on some huge PSUs.
