Ok im looking at the mini as a computer to be left on most of the day every day to be primarily used as a fileserver for home. Probably have an external HDD attached which can store all my media files and such with easy access. Is there any issues in doing so? do the parts inside get very hot and or unstable? I know the mini is marketed also as a server so im guessing that it should be able to handle long uptimes. Also I havent used a mac extensively in several years but do they still have a lot of compatibilty issues like with usb devices and some networking issues with windows pcs? Im going on the assumption that it will be a lot less of a problem these days as they are more popular. If im successful with this mini I might move most of my other products over to apple.
