My workplace ran off DL360s (the 1U variant of this) of various generations for 20 or 30 years. I remember getting the first G5 in and being really impressed by the way the components all slotted in so easily and pretty much everything was hot-swappable. And the no-nut rail system was a revalation.

They were great systems for their time but that power consumption is crazy by today’s standards!

As for feedback, you have a very confusing sentence about 2.5" and 3.5" drives being the same size. Took me far too long to realise you meant capacity and not physical dimensions!
