A Closer Look - Inside
To gain access to the interior, simply place the Tranquil PC NUC chassis on its top and remove the four screws. The interior is quite simple as there is no actual functionality built into the case itself. There are only two square bumps, which are there to make contact with the CPU and chipset of the NUC board.
Assembly
Place the four spacers on each of the corners and apply thermal paste to both components before installing and screwing the motherboard down. We removed the board after assembly to ensure good contact between the CPU/chipset and both bumps within the chassis. As you can see, all is well.
Once the board is in place, simply install the additional components of your choice. These are the exact same parts we used in our initial Intel NUC review, so temperature measurements will be comparable.
We did notice that the connectors within the Tranquil PC chassis are recessed quite far. While this caused no issues, it did keep some HDMI cables from connecting well and all the way, which resulted in slightly looser cables. Installing the power button also takes quite a bit of force and effort as there is very little space and the cables keep turning, but everything panned out in the end, and there was no damage done to either the board or the cables. This lead is then plugged into the standard header found on the NUC board.
Finished Looks
With everything in place, we put the bottom cover back over the opening and used the included screws to secure it, which left the chassis without any moving parts, or openings. The only tell-tale sign of the system inside operating is a blue LED in the back of the device. The Tranquil PC NUC case also ensures absolute silence as there is no fan inside.
