They are good, reliable cards.

Why Mandrake? Its not supported by Dell you know.
Dell currently only supports RHEL (all servers) or SLES9 (on some boxes).

Dell even supports RHEL WS on servers, so for what 70 quid you are fully
supported.

>> Anyone here using the 4/SC?  Any problems?

None to speak of.
