I've been using one for https://pikvm.org/ and it's been a rare case of "the Raspberry Pi is neither ridiculously overpowered, ridiculously underpowered, or even beat out by any off the shelf solution at all let alone at the same price or point". It's literally the best IP KVM I've ever used or owned. The use case is almost a perfect match for the exact hardware capabilities of the Pi: hardware encoding, video input, gigabit network (with Wi-Fi alternative, which has saved me a few times), GPIO, USB OTG, the hat system, open source web KVM software which doesn't suck ass and sit untouched for 13 years with endless security vulnerabilities piling up.
