i got a little more info about the Dell draft N mini PCI card: it can only work on a "mini pci express slot " , i wonder if the one on the new sentia's is a mini pci x. i went to alienware's site and could not find any more info on the Alienware® Intel® 945GM + ICH7 Chipset motherboard if it contained the "mini pci x" as opposed to just "mini-pci".
