Lol this CPU isn't locked to the mobo, it's a 5800 with a custom b550 board. The win 10/11 code will be locked to the board so you'd need to grab a key off a key off a seller. Tbh givern the tumbling GPU prices and the hassle if your thinking of a motherboard swap it doesn't represent great value in the short term. If you just want to just plug and play then it is a great deal with warranty etc.
Good deal. I wanted to separate my main pc to make a decent powered media server and have a device just for gaming.
I don't think Lenovo can take a CPU and physically make it not work with anything else.
You may not be able to swap out the motherboard and keep the same CPU as Lenovo are known for locking AMD CPUs to their own boards.
