Test System

Assembly

Installing the motherboard is done with the included screws and spacers. There is plenty of space on three sides of the board, allowing you to connect everything. Cable routing is alright, but it would have been nice had Jonsbo equipped all openings in the motherboard tray with rubber grommets, especially as both sides of the chassis are made out of transparent material.


To install a 3.5" HDD, simply add the screws and rubber rings to the storage unit and slide it into place. It is a snug fit, and the glass side panel will keep it from moving out. Due to the rubber rings, you will not have to worry about vibrations either.


Installing the SSDs is done in a similar fashion, with the use of screws and rubber rings. Once these are installed, you may place the contraption into any of four spots in the chassis. The rubber rings hold the drives in place quite nicely, so you should not have to worry about them getting loose during normal operation.


As mentioned before, the power supply needs to be pushed into the chassis through the side and is then secured by traditional screws. The PSU's fan has to face into the case as there are no air vents toward the front of the chassis.


With everything installed, the interior of the chassis makes an alright impression. You cannot really hide all the cables completely from curious onlookers because of the layout. I tried to spread any excess cable leads behind the motherboard tray around to make the final result as flat as possible.

Finished Looks

Once the side panels are placed back onto the chassis and the system is turned on, the Jonsbo UMX4 is back to that beautiful, understated look. That tiny blue LED in the middle of its power button further adds to its minimalistic look.


Looking at the front, only the LED hints at the fact that the system is actually up and running. In the rear, everything is easily accessible thanks to the well-placed power plug on the very bottom.


While you cannot see much inside the chassis due to the heavy tinting, a single LED fan could make all the difference if you want to shed some light to show off your system. In a dark environment, the onboard components could glow bright enough for knowledgeable viewers to make out specific components.
