Depending on how many you need, you should consider building them yourself. I just ordered a new Zen2-based build from alternate.de in parts and I think that's the way to go.
That's far too much detail for me. When I look at the "PC configurator" I feel like I'm drowning in details. I would need a week to research all those components. CPU is easy (Ryzen 5 3600 seems appropriate), but next comes the motherboard - and I'm already lost. Never mind the 100 different cases and the list goes on and on. I'm also not so sure that whatever components I select really work flawlessly together.
I run a pc recommender that is basically made for you. Parts that fit together with some optimizing algorithm selecting an optimal configuration for your price point. I changed this configuration a bit manually given your statements: https://www.pc-kombo.com/share/mX6w2675
This will fit together and is stronger than with a GTX 1050 Ti. If you really want a gpu powered only by the motherboard step down to a GTX 1050, or look at the (rather overpriced) GTX 1650 (though it depends on the model there). Mail is in the profile if you have questions.
Damn... I looked for a PC configurator for several hours two weeks ago and eventually settled for a 3800X. Your site managed to get me a 3900X in my 1200 eur budget (with 64 GB of RAM). Oh well, I will buy another PC in the next six months. Definitely bookmarked!
I have put together many PCs myself, and honestly many parts aren't that important.
Power supply, motherboard, SSD and Ram will "just work", given you buy a recent product from a known brand. The +/- 5% of whatever will not make a difference to most people.
For mobo, think of features you must have ( built-in wireless?) And that will direct you.
Oh please don't do built-in wifi.
It's ok to have the adapter inside, but you should put the antennas outside. Include them in the design, if you wish.
to clarify, these are vetted parts lists by a leading german computer magazine, complete with optional upgrades, videos to aid with the build process and even detailed BIOS settings.
