"I have been a happy customer of J&N for over 10 years, and my most recent experience with them exemplifies exactly why I keep coming back.
I had a computer which they had built 2 years ago recently die on me, and it was no longer covered by the warranty I had chosen. I was all ready to buy a whole new system from them, but, when I called, they helped me troubleshoot the problem instead (motherboard fail). Then, they talked me out of buying a new system, and rather just buying new components.
I shipped them my motherboard, CPU, and memory, and they tested to see if anything could be reused. The board and CPU were dead, but they were able to replace the latter free of charge by processing an RMA with Intel (it was under manufacturers warranty). They then installed the new CPU on a replacement motherboard with my existing RAM, and shipped it back (charging me only for the board, the assembly, and the shipping). I installed the bundle in my case, and am back up and running as good as new (and for a lot less money than I was originally expecting to pay).
I have never had a company talk me out of spending an extra thousand dollars with them I didn't have to, and that is exactly the kind of thing that makes me want to do business with them over and over. Despite living in CA (they are in NY), I never want to buy a computer, or internal components, from any other company."
