Hello guys,<br><br>I am planning to buy a used Lenovo Thinkpad and install coreboot on it. I am completely new to coreboot and I need help in the decision if I should buy a T520 or a T530. I read the wiki and some other pages but it's still hard for me to decide which model I should buy.<br><br>1. I need CPU power. I read that it is possible to put a i7-3940XM in a T530. Because of coreboot it should also possible to put it in a T520?<br><br>2. I would like to use an eGPU. Any differences between these two models?<br><br>3. With which model it is easier to install coreboot on it?<br><br>4. What are the general pros and cons of a T520/T530, especially with coreboot?<br><br>Thanks for your help!<br>Kind regards
