No sure about this list. Yes they are all mainstream, but with the exception of the M350 I'd choose others.I mean what about the Lian Li Q series... some seriously lovely cases there, Silverstone SG-05> , The Hoojum Cubit 3 (admittedly you have to find it 2nd hand), mcubed, streacom and the many other smaller companies around. There isn't any mention of the N-Case M1 that could be suggested as one of the best future cases...
They seem to have just chosen mainstream cases and not looked into anything else. Put some effort into any artical like that... Bring something we've not seen before.
