The official Facebook account of Zotac Italy published an image comparing the design of its Zotac MEK1 Mini-PC, launched in December 2017, with the design of the PlayStation 5. Although the MEK1 was released at the end of 2017, but this build has been updated annually, and the latest build version was released in 2019.
If we look at the dimensions, the Zotac PC has dimensions of 415.1 x 418.3 x 118 mm (height x depth x width), while the information listed in Amazon France on the PlayStation 5 tells us about dimensions of 476 x 382 x 126 mm, so they are very similar.
In terms of specifications, Zotac has managed to place, in its latest version, an Intel Core i5-9400F with 16 GB of RAM and an Nvidia GeForce RTX 2060, and beyond the visual comparison, with these very similar dimensions it can give us an idea of how Sony has designed the cooling system for the console.
As we can see with an older model below (same design, only the hardware changes) with a GeForce GTX 1070 Ti, Zotac took advantage and divided the chassis into two parts, leaving all the components on the left side except the graphics card, which has a passenger compartment on the right-hand side that also slightly occupies the left-hand side.
This graphic card offers a blower design and directly intake the fresh air from the side of the chassis and expels it from behind, a very efficient way of cooling the graphics card. Regarding the CPU, it is logical, a low profile CPU air cooler.
With this example we can see that Sony has more than enough space to cool the components, and more when the RDNA 2.0 graphics card will not come in the form of a PCI-Express card, which leaves more free space inside the console chassis. Of course, it is one thing to have space, and another to know how to take advantage of it.
