what if the person does not have any
Peripherals are not something I would like to include on the site due to both the personal nature of them as well as to avoid making the UI of the main build generator too complicated.
However I do have a prebuilt-style build customizer in the works which will allow the addition of these sorts of optional additions. This is a way off being feature complete but should be a welcome addition to the site by many.
Thank you for your interest,
