That's precisely how many consulting companies make their daily bread. Hell, nothing wrong with that. But you have to admit, it seems a bit misleading to claim that something like a server can be setup "without the assistance of someone who actually knows what they are doing."
That is a recipe for disaster waiting to happen. I've been in the unfortunate spot of representing a consulting company called in to configure a Mac OSX Server purchased by less-than-knowledgeable employees. It was a small business, about 5-10 people, that did contract-based graphic design/marketing. They loved Apple stuff, and were suckered into a completely unnecessary Xserve system, complete with overpriced external rack-mount tape backup drive. Being young and mildly tech-conscious, they overestimated their ability to manage this thing, doubtlessly egged on by some "whiz" at a Genius Bar waxing their balls about how well they'd be able to run it on their own.
Wrong. Granted, it's not hard to someone like me who does this sort of thing for a living, but managing backups was way out of their league. The backups weren't even running, though they remained blissfully unaware of this fact, and setting up network shares/user permissions was beyond their capability. This ended up costing them way more than ever needed to spend to get what amounted to a file server up and running, and I blame this on bad marketing.
Oh, we tried to convince them to sell their ridiculously overpowered server equipment before it depreciated in value, but they were insistent on using it, because it's Apple.
Misleading marketing like this is exactly what drives the borderline masochistic relationship Apple nuts have with Apple. All I can do is shake my head.
