I did this when Apple had chips in them that were actually Intel. Intel based Apple systems will work just fine! I've always thought Bootcamp is misunderstood, it's a wizard to setup the install, think of it as the macOS equivalent of the Windows Media Creation Tool. It's not a non negotiable requirement to run Windows on an Apple system. There is no
required drivers from bootcamp. Windows will install proper drivers during the install process or immediately after with Windows Update based on hardware. With that said, some small exception might exist depending on each user, like if you have an Apple exclusive piece of hardware like one of the Apple Magic mice. Since no drivers exist in the Windows update ecosystem for that mouse, you would need to get the driver out of the bootcamp package to have that mouses advanced gestures work properly. It would still work without those drivers, but the special gestures wouldn't function. Just basic left/middle/right click would work. Otherwise, stuff like CPU, chipset, network card, etc are going to be Intel compatible and is no different if it was installed in a DIY box or an OEM Apple box
The other exception is, and what bootcamp is really meant for besides the assisting of setting up the USB or DVD install disk, is installing a toolbar icon that allows to easily select the boot disk from within Windows. So you can boot back to macOS easily. Normal boot screen via native means means holding OPT key at startup to bring up boot select screen. Of course there are other ways within Windows to select boot disk but if you're primarily a macOS user they would be unknown
Now, how things work with newer Apple products with ARM/Mx chips.....no idea.
You are considering buying a mac.... to solely run windows? Why?
It's a great way to repurpose it if you already had an Apple system. But the point you're making, and I would 2nd to the OP, I wouldn't buy one for using just Windows.
You’ll have to delete the MacOS partition,
you can have both macOS and Windows on same disk.....however, totally NOT recommended to do this! better boot disks live separately
Edit: okay insert win 10 usb stick installer while the computer is off, turn it on and hold down option. Does that work?
this is exactly how easy it is. if you have ever installed Windows on a PC you can figure out how to install Windows on an Apple machine. Brings up the boot screen, then you move over to the USB stick and boot to it. from there on out it's no different than installing Windows on a PC. you can make the USB or DVD installer on an Apple or Windows machine
