Underground PC does an amazing job building gaming systems. Low overhead means low priced, quality systems. They are quick to respond to questions and do a great job building the components to match the needs of the buyer. Will build to your specs and needs. I didn’t need fancy lighting because it was going in a virtual pin cabinet so he built a small form factor system without the lighting.
Absolutely no complaints here. Requested service due to problems putting PC together, and just 2 days after everything is working perfectly. Top of the line in terms of response time and communication as well. Couldn't be happier 👍
I bought this PC and it only took a few weeks to get all built and ready. I loved it and my PC works phenomenal, recommended.
T was great to work with, he fixed a computer issue I had been struggling with for a few days in no time. Very responsive and knowledgeable, I will definitely call him again for any issues. Thank you so much!
