All in One PC vs separate desktop setup for Windows productivity, which makes mo

[Mohsin45]

Been going back and forth on this for a while and wanted to get some outside perspective. The argument for a proper desktop with separate monitor used to be obvious, upgradability, raw performance, flexibility. But the all in one form factor has genuinely closed the gap in a way that is hard to ignore for a standard productivity setup.
What pushed me into actually researching this properly was looking at how local manufacturers have approached the all in one category. Came across Viper and their all in one lineup while comparing options and the space saving argument starts making a lot more sense when the specs are actually keeping up with what most office and productivity workloads realistically need from Windows.
The part I keep coming back to is thermals. All in one designs have always been the weak point there, especially under sustained load. Has that improved enough in recent builds that it stops being the deciding factor, or is it still a genuine reason to avoid the form factor if you are running anything beyond light office work?
