This. Custom PC was founded at Dennis Publishing, the UK publishers of PC Pro, Computer Shopper UK, MacUser UK, Computer Buyer & multiple other titles. I wrote for most of them, starting out on the staff of PC Pro and later I wrote the Linux column for Custom PC for its first year. (After that, they cancelled both their columns, sadly.)

It's a good mag with a high level of tech expertise. They generously kept my free contributor's subscription running for well over a decade. :-)

Dennis seems to be outsourcing its magazines now, and CPC got spun off to an independent production company headed by its editor, Ben Hardwidge, who I know personally from our previous career intersections. They've always given a lot of coverage to the RasPi and RasPi-related projects.

Which is probably why the RasPi Foundation bought it. :-)
