While Kuo didn't disclose, this AIO PC might belong to the 'iMac Pro' series to replace the 2017 model discontinued two years ago.

There have been numerous talks about larger iMacs in recent years, often confused with Apple's standalone monitor offerings. Following the discontinuation of the iMac Pro, Apple replaced it with a 27-inch combo +, and since then, there have been no indications of the company developing a larger iMac.
However, it appears the company will rekindle plans to launch a larger iMac in 2025, following the use of similar mini-LEDs introduced on the pricier Pro Display XDR.
The larger iMac, with a 32-inch size, will match the dimensions of the 6K Pro Display XDR, sold by Apple for $5,000. In terms of design, we might expect slimmer bezels, resembling the style of the Studio Display. Additionally, Apple may remove the 'chin' on this AIO PC to provide a better user experience.
