N100 is an excellent chip to go for. I'm currently using a aliexpress special with a celeron n5105 chipset in it.. it works fine as well, but I'd opt for the N100 next time if I had to replace it.
Celeron N5105
CPU: Intel Jasper Lake Celeron Processor N5105, 4 core 4 threads,64 bit, 10nm, 2.0GHz up to 2.9GHz, 4M cache
GPU: Intel UHD Graphics GPU, 24EU, 450MHz up to 800MHz
vs
Alder Lake N100
CPU: Intel Alder Lake Processor N100, 4 core 4 threads,64 bit, 10nm, Up to 3.4GHz, 6M cache
GPU: Intel UHD Graphics GPU, 24EU, Up to 750MHz
I bought a N100 model to run as my backup server (PBS etc) and its a cracker. Debian is so snappy on it.
Also running OPNSense (in a VM) on an N5105 from an AliExpress mini box, with four Ethernet ports. Thing gets hot though, passively cooled, but I put a fan on top of it.
Also runs another VM with some lightweight docker containers. Reliable little thing.
Would also go N100 if needed replacement.
