Sony PlayStation 5 transformed into PS5 Slim with a 19 mm thick chassis
Sony has been selling the PlayStation 5 since the end of 2020, although contained supply issues prevented many people from getting their hands on one. Typically, Sony releases 'Slim' versions of its consoles three years into their product cycle, although it has introduced a Super Slim model of the PlayStation 3 too. Hence, it seems that Sony will wait until late 2023 or early 2024 before it brings a PS5 Slim to market.
In the meantime, DIY Perks has demonstrated how thin the current PS5 could be made, albeit with some caveats. As the YouTuber demonstrates in the video below, it is possible to place the PS5 in a 19 mm thick enclosure, down from the original case's 104 mm thickness. For reference, the PS5 measures 390 x 260 x 104 mm, by default.
Unsurprisingly, DIY Perks has resorted to an elaborate cooling solution to keep the custom PS5 cool. Specifically, the project relies on a custom water cooler with a reservoir that sits outside the case. Also, DIY Perks removed the PS5's original PSU and resorted to an external one instead. Still, Sony took similar action with more compact versions of its earlier consoles.
In short, DIY Perks has managed to make the PS5 run cooler under load at stock TDP settings. According to the YouTuber, his creation allows the SoC to operate 30 °C cooler than a typical PS5 when gaming. Better still, the custom PS5 keeps its RAM over 40 °C cooler than Sony's stock cooling solution, with VRM temperatures dropping from 71 °C to 44 °C. Presumably, any actual PS5 Slim will operate at a lower TDP than the original PS5, curtailing performance to help keep temperatures in check.
