I have seen this cool cardboard computer case (http://www.sustainable-computer.com), it proves the cardboard is workable, and I'm planning to reuse my mooncake box for my mini-itx (heck, hope it doesn't end up in fire burning). Have anyone use mooncake boxes as computer cases?

evolutioner,

That looks very 'prototype' like case, hehe. Your one ar?
Should make more lubang on the mandarin box (so the bad air from mandarin box masuk n keluar, hehe). Both fans (8mm and PSU) need to be adjust for better air flow.

Hope I'll get all the stuffs ready for my mini-itx soon.
