On every project I've worked on, the PC I've had has been much better than the minimum PC required. Just because I'm writing code that will run nicely enough on a slow PC, that doesn't mean I need to use that same slow PC to build it!

And then, the binary that the end user receives will actually have been built on one of the CI systems. I bet they don't all have quite the same spec. And the above argument applies anyway.
