I have. Mostly with Dell systems. Later on, there are known errata that pop up, like if you have this board, with this RAID controller, and this version of the BCM, make sure to upgrade this component to this version first, that component next, etc. etc. And of course, usually this errata always shows up *after* I've done the deed and killed the board. Dell also doesn't have a field recovery option either. I don't use Dell much any more.
