Installing the mainboard is nothing out of the ordinary. Simply place it on the golden spacers provided and secure it in place with the black screws. As you can see, even the fairly large Prolimatech Super Mega fits within the chassis. While cable management is not perfect, since the rubber covers are missing, you do have plenty of holes to route cables through.
So, now unto the one part which had me worried. To install a 3.5 inch drive, first remove the plastic lock, slide the drive into place and then put the lock back. I am shocked to say, that the lock actually holds much better than expected - shocked in a good way of course. Sure, system integrators and worried users will still want to secure the drives with a single screw at least, so it is still not the best thing, that NZXT did not include additional screws.
The same goes for the optical drives. While the lock holds the drive alright, it would make sense to use a single screw for absolute piece of mind and to avoid any annoying vibrations being passed on from the drive to the chassis.
Since there are four screws present for the PSU, you should not have any troubles here. As you can see, a fairly potent unit does not cover the bottom fan slot, so you are still free to install one here.
Once all the components are in place. Two things should become obvious. The NZXT Source 210 Elite is no champ when it comes to cable hiding and management. Sure the openings help, but they are not perfect. Secondly, you should be aware that - if you use a hard drive at the slots opposite of the graphic card, that you will cut it close for high end units. This old 8800 GTS fits, so most current, entry level, high-end ones should too.
Once everything is in place and the panels have been placed back onto the chassis, it makes exactly the impression you would want it to. Simple clean, but still good to look at. You may wonder, why there are two identical images? Well the right one shows the system up and running. As you can see (or cannot see for that matter), there is really no easy way to tell besides the noise if it is.
Thanks to the black drive bay covers, the black ODD does not stick out like a sore thumb, instead it looks like an integral part of the overall design. Turning the chassis over, we have everything where it should be. I have also placed the two water cooling tube covers in the respective openings, so that you can see what is possible in terms of such a setup.
