Messy cables are annoying no doubt,but one of the main problems are the PSUs. Now with fully modular PSUs,luckily things are easier,like this one:

The Shuttles I worked with are barebones,so the cables are made to fit the case and most of them are prerouted.
However,the NCase M1 is impressive since it can take normal components and I really hope it gives a kick up the arse to companies to start innovating in the SFF area. It seriously embarassing what the two people on HardOCP have done,and
IMHO it smacks of complacency on the part of case designers.
