On the consumer side you may have a point, on the business side they're a different company. Tons of documentation, full service manuals for every machine, the machines are basically all field serviceable, you can order basically any part as a replacement part, they're reliable, and their support is fast if there is an issue. I wouldn't go for anyone else as a business machine. Yes the power supplies arent always standard on every model, but its meant to be a business machine with warranty support, not a gaming rig, so as long as its in warranty or we can get spares its no big deal.
