Typically nothing can be used when it comes to laptop parts in desktops. Hard drives could be used. If it's new enough to have a SATA drive. However you'd need a case that has 2.5" drive brackets or you'd have to buy a 2.5" to 3.5" drive adapter to mount it. As for wireless card, is this a USB adapter? If it's not, you won't be able to use this either. Internal wireless cards for laptops are not compatible with a desktop.
