I hand built my system. It's a lot more difficult than it used to be.
Check the specs on everything to make sure for example, that your ram clears your cpu cooler, and your coolers fit in your case, that kind of thing.
Also power and heat. Systems are pushing thermal limits these days, so it's not uncommon to find even commercial PCs running on liquid now.
Mine is an air cooled system - maybe the last air cooled desktop I'll own for the foreseeable future.
I had to downgrade from my target CPU and I played it safe and got a 4080 instead of a 4090 GPU.
I also dumped a ton of money on Noctua fans and slaved over my cooling situation until it was all as perfect as I could get it.
I'm happy with the machine but I never want to do this again.

That's the fun part! I check and double check everything - even though ATX is supposed to be a standard, not every manufacturer obeys it. I buy cases that have more fan mounting locations than the motherboard can support. I buy motherboards that have more RAM slots than I expect to need. I get a better CPU than anything I run really needs. Overkill is always the order of the day. Recently I had to do some upgrades; I installed a new monitor after breaking an old one ( never attempt to re-assemble a Colt .45 ACP Model 1911 whilst sitting in front of the display ) when a spring-driven part went through it. I wish I'd taken a picture of the quite colorful but useless display afterwards, and had Hunter Biden sell it for me. Anyway, the new display whined constantly about having the wrong resolution set, so I upgraded the video card to one that can handle it. Turns out that my PC can't handle that much data flow, and I have to reduce the setting for it to function at all. Curiously, this card doesn't have an integral fan, and doesn't need one! It works great without extra cooling!
I might even keep this one as a file server and build something new. I actually enjoy it, but the learning curve on this job is huge. I've read thousands of pages of equipment manuals during the past week, pored over site plans and design documents, and just acquired today another 15 - 20 thick documents I haven't even unzipped yet. Time is becoming precious - just a trip to the jobsite is a four-hour round trip. I've not heard of Noctua fans; why do you prefer them?

Noctua fans are very quiet, move a lot of air per noise/RPM, and last forever.
They are overengineered monsters. I don't know a single person that has them that doesn't love them.
The only downside is they can get spendy, but it's one of those products where you'll be reminded of where the money went.

I am pretty happy with my BeQuiet! setup. I haven't got the fans to high speed yet, not even with 3 LoTRO instances, 2 VM Instances, around 15 browser tabs, a couple of office apps, a zoom conference and something else all at once.

After HP, Lenovo is the second one I would not buy if I have another possibility. I have had several in my hands (some of them from family / relatives to repair / configure something) and I didn't like it.
They might be good machines, but I am not comfortable with them.

My current system is a 3 y/o lenovo ideacenter tower that I bought on impulse off the shelf locally. I was really disappointed when I pulled the cover...very little room for upgrades/expansion as there are only 2 SATA headers and memory maxes out at 2x8GB!  The spinner was swapped for SSD immediately and fresh Win10 pro installed.
While the system generally performs OK, it starts getting sluggish when available memory drops below 2GB. Debugging some ASP.Net apps is excruciating as it may take up to 10 minutes to startup from a simple edit! (and of course Edit and Continue almost never works, so stop, edit, start, and wait for another 10 minutes!  (sometimes I miss the simplicity of classic ASP!) 
I'm already in the mindset of replacing it now, and leaning towards the build camp after this last experience.

For "field work", I can't see using a desktop or standard laptop; I'd be for a "Toughbook" with all the obscure port options, etc. Extra monitor.

You might want to also decide who is going to own the equipment. Presumably you will move on at some point and someone else will replace you but the work product will presumably still belong to them. So if it is their equipment it makes that part of it easier.
If it is their equipment then they would also be paying maintenance. With a standard maintenance support using a standard build is going to be easier. Also easier to replace it if that is needed.
Additionally that still leaves you the option to build your own personal PC. You do not necessarily need to 'build' it fully of course. Either custom design it fully or by something basic and perhaps upgrade a couple of things.

Good point.
I have had several brands during the years and the best "gold" support in my experience was the one from DELL, sadly I am using HP due to company policy since 2015.

Good points, all. But this will be "my" computer; I will do company things with it, but that will be kept isolated from my stuff. Heck, they haven't even designated a place for my office, and when they do I'll get equipment that's to their standards, if they have any. These good people are really in the infancy of creating a real utility, and I'm hoping to help them to build it into something that will serve their tribe for decades. If they have no standards in place, I'll help them to create them.

You first need to decide whether you want a desktop machine or a laptop. If all your work will be done in one place then a desktop be OK but how likely is that really? I use a lot machines that are classified as "gaming laptops" and they work really well for me. I like 17-inch displays because the pixel density is better for old eyes like mine. The main things that makes them a "gaming laptop" are fast displays and a good GPU. The CPUs are usually pretty good in them also. After I broke my last laptop I bought a new one and it's a pretty good machine. It's an Aorus which is made by Gigabyte. At work we have dozens of MSI gaming laptops and they work really well for us. I would highly recommend both of those brands. You could always get a decent-sized monitor to use with it if you want a bigger display and LCD monitors are reasonably portable. With a mid to higher end laptop there is very, very little they can not do. I also do CUDA programming so I get them with Nvidia GPUs and they are quite capable. I have a 3080 GPU in my work and home laptops and it is very nice. 3D graphics are no problem at all for them.
The last desktop machine I bought was pre-built because GPU prices were obscene when I got it. It was like I bought a GPU and they threw a computer in on the deal. I would probably not advocate for a desktop machine though because it really limits your mobility for no good reason that I can think of since laptops are so capable these days.
Incidentally, with the nature of our work, we find the lighted keyboards to be really, really useful. I wouldn't want a machine without one now.

This is going to be a replacement for my home PC, so it's going to be a desktop. But I do have a decent laptop for use when travelling, and I'm not opposed to upgrading that, either. Our own Honey the Codewitch turned me on the Daskeyboard series lighted keyboards, btw, and I love the thing. I will definitely be getting another when I buy/build the next machine!

build all the way.... I have seen so many shortcuts made by Dell, HP, etc I swore never again. The machine I built 10 years ago is still thundering along in my daughter's bedroom. Glancing to my left at my Ryzen 9 desktop server, it's been thundering along on Windows 10 for 4+ years and has never crashed once. Since I suspect you are not building a gaming rig, you just need a good chassis, SSDs, a good power supply and a motherboard perhaps with a built in graphics chip, though I would argue for a standalone.

I configured one last night at Newegg that should last me another ten years, I think - about $3500 though. I may rethink that a bit before I pull the trigger...

I have machines going back probably 20 years. All purchased as is. Added a few things probably to each but nothing significant. And I am certain all of them would run if I just turned them on because I did not move on from any of them because they were failing. I suspect the older ones are VGA and definitely have serial and parallel ports. Probably a modem card.
Actually machines even older than that which still worked I got rid of just to free up a bit of space.
I actually have 3 CRT monitors that still work too. And a HP Laserjet.
But I wouldn't want to try to run any of the games that I play now on those older machines.
Although I do still use a soldering iron that is at least 20 years old.

Here's a system I configured about a month ago. Has 2 options for the processor depending upon what you want to spend. I bought the nVidia 4070 (non ti, saved about $200) video card and have been pretty happy with it. Pick your case (I'm a fan of the Corsair cases as their no fuss water cooling works great with them).

Nice! Thanks for sharing that. I may want to back off on my 24 core selection of a twelfth-gen i9 processor. They're a bit pricey.

I used to always build, but on my last machine, I decided to go with a good custom builder. I don't know what country you're in, so I'm not sure what would apply to you, but this is the route I'll probably go next time too (I went with, and would use again, WootWare - wootware.co.za)
I won't buy some off-the-shelf junk - companies tend to stuff them with the lowest-spec'd rubbish they can get away with at a price-point, or put totally mediocre hardware in the box and charge $arm + $leg for it (GamersNexus videos cover a lot of these charlatans!).
I'd suggest finding a local company which builds based on "loose" specs and which has a good reputation for service, so if something goes wrong during shipping or something fails in the machine, they will help with RMA'ing things.
For reference, I spec'd the following for my machine:
- latest-gen i9 (11th at the time - 12th came out a month or 2 later... but I couldn't really wait)
- 64Gb RAM
- board supporting the above, with Wifi & Bluetooth support, either on the board or on a daughter board (ended up going that way)
- Liquid cooling
- Minimal lighting (but I ended up with more than I originally anticipated, and I kinda like it)
- Chose a case that I like, looks-wise and rated online as tough and easy to work with (Phanteks Ethoo EVOLV)
- Originally kept my GPU, but then bought a GPU from them - it's a minor installation
- One NVME drive, if the overall cost fell within my budget (which it did)
Whilst they did suggest an AMD machine for a slightly lower cost, they also didn't shove it down my throat, and respected me when I declined (a good friend of mine had been having an uncommon issue with his AMD that I was afraid I'd have, and I didn't feel like enduring the RMA cycle for a minor price difference - about 1.5% on the entire system)
What I got
- 11th gen i9 11900KF (can push the clocks - which I'm not - but no igpu - which I don't need)
- 64Gb 3600mhx ram (2x32)
- Gigabyte Z590 Aorus Elite
- Fractal design cooler
- The Phanteks case I wanted
- Sabrent rocket nvme (which I wouldn't recommend, tbh - tends to overheat in a pcie-4 slot, though the Windows drivers just slow the drive down when it's heating up, so you won't notice in Windows - just the drive will get slow; but under Linux, the drive goes offline...)
- later, a Gigabyte Aorus 3070
The experience was great - I had the fun of picking out what I wanted, with the safety of not having to double-check that I hadn't picked anything incompatible. I then got a beautiful, powerful machine without the stress of potentially damaging expensive components. I was up and gaming that day, no sweat, no stress. I had an email trail about 10 deep going back and forth, refining the system based on costing and requirements - this is why I say: choose a company with good customer service. I'd emailed another company (evetech) and the guy got back to me, obviously annoyed with my email setting out my requirements, having missed part of what I asked for - and 3 days after I sent the mail. Wootware got back to me within a day with the AMD recommendation, and turned around with a similar Intel quote within a few hours of me pushing for Intel.

I pretty much always build my own these days. I like being able to control all aspects of the build. About the only time I didn't building my own was when I got an Amiga (loved that machine). Unfortunately, Commadore was run by a bunch of morons so the Amiga didn't survive. In any case, building computers now is much easier than when I built my first computer back in 1978!

'78 eh? Yeah, that was challenging! I had just finished building an Altair 8800 about then, and changed jobs to design hardware and program HP minicomputers. I didn't get around to building systems for myself until IBM set the standard for what we call a PC today. Good times, and so many more choices to make today!

It was definitely fun and was a great learning experience. Bought the CPU card and the buss board (S100) but the rest of the cards were my design and were wire wrapped. A 4K RAM card, a dual serial port card to start.

I'll late to this , but what the heck ...
I see buying a PC already built as outsourcing your PC or workstation requirements, versus building your own from parts that you have to research, trust and test to see if you get the performance and reliability that you need. It becomes time consuming, where that time could be spent on actually using the computer to perform your craft. The downside to building your own is that retail parts most times don't match the much higher quality of OEM built parts, like in the old days when you bought a retail hard drive, that drive was sub standard and didn't pass all the tests to be an OEM drive that a corporation would purchase.
I've been using Dell Precision workstations since 2011, and have no regrets. I just bought another last year (Dell 5820) and put a 10 core Xeon in it, and one of those NVidia cards RTX-A4000. I don't need gaming speeds, just reliability where I can run the computer for 12 hours straight with no issues, for at least a decade. As far as cost goes, it's almost the same to me, but the little details like not really needing tools to work on it is nice. But I have the computing power to do what you described no problem and really quick. You can call Jose at Dell for a good price if you choose this route. Just PM me for his email or phone number.
