I would like to create a custom aio loop for INTEL i7 1200K with a very small PC case. What do I think if I use these components:

Alphacool NexXxoS ST20 HPE Full Copper 120mm Radiator

Alphacool tube AlphaTube TPV 12,7/7,6 - black matte 3,3m (10ft) retail box

Alphacool Tec Protect 2 Clear 1000ml

do you think the CPU temperature will be excellent?

I dont think you will get enough cooling performance for an i7 12700k with this setup. I would recommend a 240mm radiator.

For reasons of space, this could be an alternative: Alphacool NexXxoS ST25 Full Copper 92mm Dual Radiator (184mm)
Or do I need to install at least a 240mm radiator?

Let me put it another way. The 12700k has 210W of waste heat at full power output. A 120mm radiator is not enough if you want it to be quiet. If you don't mind a 1500-2000rpm fan, you can cool the CPU with the 120mm ST20. But usually you want it to be quiet. But 210W also need cooling space. The Intel CPUs are hotheads. And the 12700k is not much cooler than e.g. my own 12900k. There is only about 20W difference between them.

If it should be quiet, a 240mm radiator is mandatory. If the volume is not so important, you can also try it with the 120mm. I just can't recommend it with a clear conscience. The 92mm radiator would definitely be overpowered with the CPU though.

If you want to use a small case, you have to live with it. We unfortunately often have customers with SFF cases who think they can cool their high end hardware in it with small radiators. but physics has its limits.
