This news may not excite too many folks out there, but I imagine one or two of you are interested in using a PowerMac or Mac Pro as a server. Doing that correctly means you need at least 2 ethernet ports but sometimes even that isn't enough. Luckily for our server wanting friends Small Tree Communications has just released their Single Port Copper Gigabit Ethernet Desktop Card for PCI Express Power Macs and the Mac Pro. This $99 PCI express card adds a single 10/100/1000 baseT ethernet port to your Power Mac or Mac Pro. Not too shabby.
