The feet are larger and have pretty shiny rims and vibration-absorbing rubber pads.
The chassis shows a high quality of manufacture. Everything is rigid, the edges are all neatly finished. For the side panels not to rattle, special springy pads are used instead of folded tabs.
Take note of the amount of holes in the mainboard’s mounting plate. There are more of them than required by the ATX and microATX standards. The fact is the system case complies with the Compact Electronics Bay standard that allows for building dual-processor systems in tower-style cases. CEB mainboards (you can read CEB documentation here) do not differ much from ATX mainboards. They are a mere 3 millimeters wider and partially coincide with their mounting holes but CEB describes that CPU coolers are fastened through the mainboard to the system case. That’s the reason why the Ikonik Zaria has so many holes.
There is a bottom vent hole with dust filter. Ikonik’s engineers seem to think that the option of installing an additional intake fan may be interesting for users.
An unhandy plate is still used to fasten expansion cards. The expansion-slot brackets are now reusable.
Screw-less fastening is used for drives in the open bays although the mechanism is somewhat different from what we have seen in the Ikonik Taran. The devices are held with prongs on one side and with a spring-loaded plate on the other. The prongs are now extended by using a special lever rather than turning a handle (they retract when you press a button). Anyway, you have to remove the front panel to install your optical drive.
You will have to take it off often, though. It is in the front panel that the filter of the 140m fan, located in front of the HDD rack, is fastened. Perhaps it is technically more difficult to install it inside, but that would be easier for the user (the HDD rack is detachable to provide access to the fan).
HDDs are installed into the rack on screw-less rails. The rails provide protection against vibrations: the HDDs touch the rails via damping pads.
