Mark is extremely helpful. When I first reached out to him, I thought that he might sell laptops. He doesn't, but he was more than happy to help me decide what would be best for me. He sent me an email of recommendations based on what I told him I was looking for and told me to feel free to text him with any questions. I did and he was always helpful and responsive. Thanks to him, I felt very confident about my purchase because he really understands computer hardware. He did all of this for free, just to be nice.
In addition to that, I had been having issues with my desktop and I live in Flagstaff. Mark was able to help me remotely. He determined it was a hard drive issue and gave me a link to one on amazon to buy. When I received it, he told me how to hook it up so it could be cloned. He cloned it and then gave me instructions for putting it back in. I had a few struggles because I pulled a cord out of the motherboard accidentally, when switching out the hard drives, but he was able to help me identify which one and direct me on where to plug it back in. He's very generous with his time in addition to being knowledgeable. (And he knows C++,which is awesome). Definitely would recommend him for any computer related needs.
