How well-supported is the Dell PowerEdge 1800 (RAID, management, etc.)?

[Darren Pilgrim]

I'm looking at buying an off-the-shelf server, of which a Dell PowerEdge
1800 is an option.  The features are what I want and the price is
excellent, but of course Dell can't tell me how well it works with
FreeBSD 5.x.  I'm looking for:

Success stores, gotchas, gripes.

Is the SMB/BMC supported for the usual system monitoring (fans, temp,
memory errors, etc.)?

Does the amr driver produce/log a disk failure?
