Mine stuck in the PCI-X133 (the x345 doesn't have PCIe). It should be
able to provide decent performance. However, even given that decent
software for management is provided, I like to go the ``it's already
supported out of the box by the OS installed'' approch (I must confess
that I really like OpenBSD in this regard)...
