Wireless adapter options for HTPC
I just bought an older computer to use as an HTPC, but overlooked the fact that WLAN has not always been standard. So I'm going to have to add it myself. I was planning to get a USB adapter, but I don't necessarily want to sacrifice performance for mobility or ease of installation. It seems like the USB adapaters are generally less expensive than the PCI adapters, too. What should I go with?
