You can use any hard drive that is ATA type, any brand any manufacturer. That machine will only let you format a drive to a max of 128GB. That is to say you can buy larger than that but it will only see 128 GB. As for processor upgrades here is a link to some. http://eshop.macsales.com/shop/accelerators/ The airport install in very easy no tools required. Open up the case I think you will be surprised as to how easy it is to upgrade the machine.
