Depends very much on how many of those you have. We have one AMD Threadripper box and one Mini for builds and some other various machines for testing, and we've had to screw with one of them maybe once a year. Modern machines are less finicky than older hardware. Spinning disk is almost dead, and if you avoid it you've eliminated most of your moving parts that fail often. Fans are the only other thing. Solid state hardware can hum away for years and years. This is for small scale of course. If you try to run a larger scale DC it gets to be a pain since even with rare failures they will now happen often if you have tens or hundreds of machines. I wouldn't try to run a DC these days unless there was a compelling reason or a huge cost saving.
