I needed an extra NIC for my
HP ProLiant MicroServer, which meant finding a low-profile PCI Express card with a half-height backplate. This adapter came with a full height backplate fitted but the package also contained a half-height one that can be used as a replacement - a very quick process involving two small bolts.
I'm running Fedora 16 on the server and it runs perfectly using the e1000e driver, both connected to a VDSL modem in 100 Mbps Full Duplex mode, and also connected to an HP Procurve switch in gigabit mode.
I'm delighted with this good value card.
