As we said in the Introduction, system cases of this class rarely betray some serious defects. But if you want to shell out for one of them, you should approach the problem of choice responsibly as each of them is only good in its own way.
The Cooler Master Cosmos 1000 leaves the impression of a system case that allows building a top-performance but low-noise computer. It has everything for that. As for minor drawbacks, we guess this system case is not handy for tinkering with the components often.
Corsair gets our praise as its debut Obsidian 800D model will surely enjoy a warm welcome. It seems to be the most versatile product among the three and is one of the few that offers a 4-disk rack (with the hot swap feature) accessed from the front panel. It is also going to be good for users of liquid cooling systems. We guess the single notable downside of this system case is that it is too large and heavy. As for minor drawbacks, it lacks any kind of dust protection on the vent holes of its top panel. It does not have an eSATA interface and the ventilation of its HDD rack could have been better.
The Lian-Li appeals to the eye with its unusual exterior design more than the other models. Being shorter than its two opponents, it not only allows installing long expansion cards but also ensures excellent cooling for them. The biggest problem about this enclosure is that HDDs installed in it are going to produce too much noise. The nonstandard position of the 5.25-inch bays is a smaller drawback: it is not always handy to have your DVD drive’s tray extending sideways. Users of various kinds of control panels may also complain that there are only two external 5.25-inch bays available in it.
