In addition to the case being attractive amongst your equipment, if that is where you will place it, sooner or later your most important consideration will become noise from the various fans in virtually any self-assembled PC.
In order to have a very quiet case, my experience ultimately led me to look for something with large case fans that can rotate at low speeds. I have given up the looks of two Silverstone cases (and they can be very good looking even amongst Levinson equipment) to go to a tower with 120 mm fans with speed controls. The case I selected was a Tsunami, looking somewhat like the vertical Theta power amps, but without the machined surfaces. Available in both black and silver.
