:Q Why so much?
I've also often wondered who case companies use to 'fabricate' their aluminum cases. You know, companies like Cooler Master, Lian Li, Silverstone ... what kind of metalworking company do these guys use? Are there "aluminum fabricators" or something or ???
This is all assuming these companies don't use their own foundry & do their own metalworking -- I assume they draw up their designs and then send them out to ________, and those people then physically make the case?
CoolerMaster, Silverstone, etc... They don't make cases. They design bezels. The cases are made by companies that specialize in making cases. Bezel molds are relatively cheap (about $20K) so they'll just make a new bezel mold and put it on the same ol' chassis. And for the record: The bezels, unless they're aluminum, are typically not made by the chassis manufacturer either. They're usually made by a company that specializes in ABS.
Lian-Li is expensive because they make their own product and don't OEM for anyone else. On the other hand, they're not that much more expensive because their margins are slim and they don't have to pay a middle man. Typically, once these other cases change hands between four pairs of hands, the street price is easily double the actual manufacture costs.
New chassis molds are about $100K. That's because they're giant presses that the aluminum is stamped into.
The laser cut case is so expensive because of time. The G-code of the case drawing has to be loaded up into a CNC machine. The CNC then controls a laser that cuts the panels. The panels are then hand riveted together. This is typically how prototypes are made prior to investing in a new mold. The cost for one of these cases is usually about $1000.
