Hello guys, First of all, really appreciate this project and I want to thank to all of you guys sharing your experience and creating such a great community. if there's anybody that managed to do it successfuly on this Thinkpad model, please PM me so I can talk with him, and I promise at the end I will post a full guide for this type of Thinkpad (wasn't able to find more that 2 posts related to this type of Thinkpad, and at one nobody responded, the second one I cannot find it anymore). I decided to start my own eGPU project, on my Lenovo Thinkpad T420s. I have waited for the PE4C-EC060A V3.0 ( eGPU PCIe x16 interface for ExpressCard) to be released and decided to order one (since Thinkpad T420s has an Express Card port) but instead I ordered an PE4C version 3.0, PCIe x16 interface for mPICe; Length 60c and it has been shipped. I than opened my laptop and I've noticed I do have a 2nd mPICe slot, and here comes my first question: 1st question: do you guys recommend me in switching to the Express Card version, or the mPICe one behaves the same as the Express Card one? The only inconvenience is that it will be harder to plug it in and out, since I take my laptop to work at a daily bases. Looking at the requirements, I saw that it is possible to do it for this type of laptop by having a bios version of 1.3x. 2nd question: The bios version of 1.3x refers to the bios versioin developed by @Tech Inferno Fan, or just the market one? ( I currently have 1.31 installed). I than need to consider what GPU to order. The post that I found about GPU installed on a Thinkpad T420s, it was talking about an Geforce GTX 570 (from what I remember - this is the post that I cannot find anymore) . I was thinking about buying an GTX 750 Ti OC2 2GB, beeing a 3rd Generation that seems to work with the PE4C V3.0, but while reading the forums, most of the guys installed a 2nd Generetion GPU. 3rd question: Does anyone know if the PE4C v3.0 Gen3 is stable or it';s safer to go with older GPUs. That's it for know. Thanks and really appreciate the support. Regards, Strack
