I'm building a HTPC using the Monarch Hornet case. It has 2 PCI slots + PCI express for video card. Its a Winfast Foxcon motherboard. I didn't do enough investigation and I now find the SPDIF out is a 3 pin connector on the mother board.....no header for external connection. So I need to find a backplate (which will use one of the pci slots) or add a sound card which will also use a pci slot. I need a wireless adapter......which will use the remaining pci slot, SO, the question will a USB wirless adapter from Linksys provide just as good a connection for networking as an internal network adapter? Anyone used one of these? They are for sale at Sams with theLinksys wirless G hub.
