9th gen can work on any 300 series chipset officially. However, a BIOS update may be required depending on when you bought the motherboard.
 
If you require Intel, then how about instead of going with the mainstream platform and go with the Xeon E CPUs on the LGA1151 platform? (specifically the 6 core CPUs)
 
For CAD, the 8700K and even the 8700 will beat the 9700K. Specifically something like Autodesk Inventor Pro 2019, that will use up a bunch of threads, at the very least from what I have seen it can take advantage of 16 threads (out of 16, on a Ryzen 7 1700 system), maybe can use more but I personally haven't tested it.
 
If you need reliability, you will want the Xeon platform, not necessarily the i7-8700. I should add that the 8700K does have all the business features unlike previous unlocked CPUs.

I've never needed ECC ram for CAD, but if the user will be doing heavy FEA simulations then ECC will be good to have. The far more critical thing is the GPU-- a cheaper Quadro may outperform or enable features the RTX 2060 won't allow. This is highly application dependent though.
 
I'd go with the stock 8700 and not overclock anything. Reliability and warranties are key for a system you rely on to pay rent.

the 450 watt PSU will still be enough (I have my own rig posted in my signature and its power draw, for reference)
what good does the 2070 serve in a CAD machine that's not doing renders? I think it might be more than you need.
 
The Elite 130 is rather ugly, and the layout of the C10 has much to be desired, but it's more workable.

These will probably all be combined in "new builds and planning"
 
Anyways, my mini ITX senses tingled so I came as soon as I could.

If you'll insist on this motherboard the i7 8700 locked is realistically your only option.

I don't think you should really bother with the i7 9700K over the i7 8700.

That's an awful system. Expensive CPU with a cheap ass 50€ Board? That's asking for trouble - and failure.
 
You should look at Ryzen 7/2700(X) or, if possible wait to the end of last month.
 
As a Board: An ASUS, maybe ASROCK Board.
Since AMD Supports ECC RAM, i'd recommend the fastest ECC RAM for a PRODUCTIVE SYSTEM!

I would stick with 8th gen. 9th gen chips would normally require at least a Z390 board.
 
I would go with the B360-I, I don't know what the H310 is, but the B360 is something I know.

The 8700k when overclocked can handle your CAD situation, but I don't know much about CAD and how it uses more cores / threads.
 
I would personally go HEDT for a CAD workstation.  64GB 3200Mhz and drop in a 9900k which is soo cheap now 480 bucks only.  Slap it on a gigabyte Z390 board

Wich to me sounds like ECC RAM makes sense as 1bit Errors can get corrected and that might happen with a 24/7 System more often because of that.

ECC RAM, although not as fast as non ECC RAM (because nobody makes faster RAM), gives you the extra percent or two of Stability for a productive system.

8700 is your only worthy choice if you're limited to weaker boards

Are you Serious?!
A PRODUCTIVE System needs stability, you can't afford to tinker around with it!
 
That's why you usually don't make it yourself.
In that Case I'd tell him to get a DELL System for that.

Because I don't se any reason it has to be Intel, especially since AMD Supports ECC RAM in Desktop CPUs (even if its just inofficially), though you need a GPU for that.
Ryzen APU do not support ECC.
 
 
And no, AMD CPU are not less stable, thats utter bullshit from 25 years ago, when people went cheap all the way on AMD, with NoName PSU and the broken RAM from the shop.
 

Yep. If you're just doing modeling and no rendering, the 8700 would be your best option because it has the performance that would get what you need done.

Go b360-i and get the 8700. If you don't need to get super fast CPU speeds to render, you'll be fine with the non k.

Well, my signature speaks for itself in terms of case suggestion.
 
As for your other ideas:
Pretty big gulf in all of these, and stay the hell away from VS for any semi decent build. SFX makes building in ITX more convenient, but the Sugo can accept a full size ATX as well.
calculators just aren't trustworthy, If you're looking at a 6 core i7 and a 2060 ish graphics card, you will likely draw close to 300 watts at most, so a 450 watt PSU would do quite nicely, as this is the lowest wattage you'll find a good PSU at.
 
These little silverstone PSUs are also good to consider:

since the Sugo doesn't come with a front fan, I recommend a single 120mm fan of your choice LED color for style.

I'd opt for a better mobo as well. Ie. B360-h370 chipset or b365.
 
Rtx 2060 would be optimal with 450 -500 w units. Bitfenix whisper m, corsair rmx/txm, seasonic pr1me or pr1me ultra , be quiet straight power for instance. I guess most itx cases take regular psu without issues
