New DAW build upgrading my StudioCat Q6600

I have deleted my original post because it was misinterpreted as a negative comment of Jim Roseberry.  All I was asking was for suggestions regarding the build.  I did comment that I had contacted several different builders, but I certainly did not indicate any problems with Jim.  There are several good commercial builders who specialize in building DAWS. Jim (Studiocat) and Scott (ADK) are the only ones who I generally see post here and gearslutz. There are other professional DAW builders out there.
 
When I make a significant purchase that I will be working with every day, I feel it prudent to explore all reputable avenues and "kick some tires".  I personally do not feel this is disparaging anyone.
 
There is nothing wrong with my Q6600 system. It works great.  I use it every day.  I just feel it is the right time to upgrade to a faster system.  The new build is specifically designed for low latency, high track count recording. The more I learn about the art of recording, the more I ask of my  computer.

Of course he is still in business.  Well aware of that.  Great guy, great service.   He is one of the DAW builders I have contacted. I am not asking about who  but rather an overall  take of the build.
thanks

After considering all factors, I have placed my order with Jim Roseberry. He has always provided excellent service, though truthfully, I have not really needed anything fixed.  I would also say that being a returning customer has its advantages

While going thru some records I realized that the Q6600 system Jim built me was ordered in Feb  2008! Five years without a hiccup. It still will run almost any mix I do.
