I have used M93P and 9020, both work perfectly well, but the Del heats a lot.
1 of M93P and 2 of 9020 are in use daily for several years.
Be aware that even getting the exact same model sometimes will not work, something as simple as a dried capacitor can render any of those PC useless for machine control and be perfectly OK for normal use.
If you can test before buying, download the official ISO, write to USB and use that USB to test the PC using one of the included parallel port configurations (does not matter if the PC has the port or not), might not always work, but if it does leave it running the test gcode and play some youtube videos, maximize and minimize the screen several times, let it run for half hour. If you get latency warnings for the base period, it still might be OK, but if you get servo warnings, shut it down, test another.
Gotcha, sadly I can't check them beforehand so I will just go with one that looks "clean", not dropped too often, not looking like it has been running in a dusty office non-stop for 8 years and from a seller with a good rating.
But good to hear you think both brands will do well. I'll give some thoughts to the Dells running hot though as I am in the tropics. AC is incoming for the workshop, but it will still be on the warm side - the AC is as much for my comfort as it is to keep the humidity and rust down in the workshop.
So, here's the thing, I can't test anything, at all, ever before buying... Reason being, I am sourcing all of this from China. I used to be based there for work, but now I am on an island in the Phillippines, so I buy everything pretty much sight unseen and most of it from China and it gets here a month or so later. I've bought servos, servo drivers, VFDs and a bunch of smaller bits and bobs all used and was about to buy used (Japanese) linear rails and ball screws for my own build when I came across an almost fully functioning cast iron router in the size I needed so I jumped on that instead to get started cutting as soon as possible. But pretty much every items has been as advertised or better and some of the deals have been sweet.
Anyhow, all this just to say, I have to hope my luck isn't about to run out as the PC and touchscreen will also be secondhand and I can't test them beforehand... But the secondhand apps in China are now like Ebay in the early days, good deals and honest sellers who go out of their way to make sure any flaw is properly depicted.
I'll probably jinx it just be thinking this but with the money I've saved so far on these buys, I can afford a lemon. But yeah, hoping not to get one, of course:)
