No but with the raspberry you're not there without a power supply, case, cooling and storage.
Add them up and a Quad-Core N100 becomes equivalent. Here they're on Amazon for 180€ with 16GB ram and 512 GB storage. And cheaper options with less storage and ram (usually coupled with the sightly slower N95 chip)
It's not a pi and if you want to integrate it into electronics a pi is much better but for the "small mini server" usecase I don't see the benefit of going for a pi anymore.
