Jim's name comes up usually within the first few posts here on this subject. I've never used him but many have happily had him build their computers. He offers a pretty good deal.
I would like to see some competition though. Either that or make him the officially recognized Cakewalk computer builder. I know there are others who do it as well. We just don't hear about them as much.
I think most of the big name daw builders are over priced for the tech they offer. JMO YMMV. They usually drop back a generation or two to assure there are no issues or offer a minimum build for your needs at a higher price. Chips and builds having been on the market awhile are proven and less of a liability for them.
At one time there were more fixes that could be done in software that would streamline a machine for daw work. With more recent OS and better hardware performance many of these basic issues are now moot. At one time I think you needed to lean more on a pro computer builder who knew what needed to be done. Much of this was more software related than hardware related. I don't believe we need that as much anymore.
Many report great results with high spec'd mass factory built computers. Even the basic ones can record smaller projects with no problems. The hardware in mass made machines is reported to be of less quality in many cases. How this actually plays out in terms of years of reliable use is anyone's guess. Especially if you have a good replacement repair warranty in place.
While I would recommend you either have a better machine built or build it yourself, this isn't always mandatory all depending on your needs. Of course buying the bottom tier machines for audio work is always asking for trouble.
I built my own after some brief research and I saved a lot of money in doing it. For me it's just assembling parts and loading the OS. It can potentially get complicated, but much less so if you use good hardware.
I don't want to be the one to tell you to build your own, because all of those who bought from Jim or another similar will say, " I told you so" if something doesn't go right. I was willing to take that chance and it payed off for me. For those not technically or mechanically mediocre a builder is probably best with a higher spec'd factory computer being a second option.
The reason my name comes up a fair amount... is because I've been part of the Cakewalk community since the CompuServe days.
Speaking for my company:
We offer the latest generation i9 (Skylake Extreme) architecture.
Caveat being only the top-tier 7900x offers 44 PCIe lanes. The mid-tier 7820x (and below) are limited to 28.
For simple builds, 28 PCIe lanes is fine. For more complex builds, 28 PCIe lanes can be limiting.
ie: X299 motherboards offer three M.2 Ultra slots. Each of these requires 4 PCIe lanes.
For more complex builds, the 6850k (Broadwell) is a better mid-tier choice... and still a quite formidable CPU.
We do NOT offer Ryzen/Threadripper... because the first generation motherboards are super flaky
(I've covered this in numerous threads).
If you think we're over-priced for what we offer, consider that we have to warrant the machine (top to bottom) for two years... and offer lifetime technical support.
If you want to see more competition, I invite you to try and do the same... do it for less... and manage to stay in business for 20+ years (to be around to support your clients).
Whenever this subject comes up, it's a little ironic...
If you threw out any career... I'm guessing someone could make statements that those services are over-priced.
Mechanics, Doctors, Lawyers, Contractors, Financial Advisers, CEOs, etc...
Speaking in general terms about performance:
In
any high-performance application (doesn't matter what type of machine; cars, computers, etc), you're always best off with a machine custom built for that exact scenario.
It's exactly what you need. Nothing more... nothing less
If your company's business is racing automobiles, you probably won't do well with a stock Toyota Prius.
