Lancool Metal Boned K10 brings the best of both worlds: its exterior is made of aluminum, bringing a flawless finishing and being lighter than all-steel cases and, at the same time, its internal body is still made of zinc-coated steel (a.k.a. "SECC"), which makes this case to cost far less than all-aluminum products . This case is particularly targeted to users that go to LAN parties, not only because it is lighter than other steel and hybrid cases around, but because it presents a very robust construction and a couple of small features to prevent unauthorized people from opening your case.
