Well, I've asked her before whether she wants to use ethernet or Wi-Fi for her internet connectivity and she didn't really know what I meant, so I thought it would be best to give her the option of wifi if she needed it. I believe the build I put together already has a wired internet card already , so that shouldn't be too much of a problem if she does want to use that. It could always be removed from the build if needed.
I might be being dense here but have you only really changed to an overclockable chip/board? Because as far as I know, they don't even really understand what overclocking is and so I doubt they would be doing it.
Actually, if they wouldn't be overclocking, would it even be needed to replace the stock cooling?
