Fewer people than ever are comfortable doing that, even though the information on how is easier to get than ever.

I hope a repairable and upgradable Steam Machine would help more people dip their toes into it.

I fully understand being uncomfortable with a CPU swap, but a GPU swap isn't difficult.

Valve also could have gone the Framework route of releasing a motherboard+CPU combo so you can upgrade later down the line just by swapping the board out.

I guess they can earn more money by soldering everything on the board and having you buy a completely new PC every time you want to upgrade.
