Have an option to add SSD
I really want to see builds without an SSD, as I don't think they are completely necessary. So you could add the option next to the Include Windows button.
SSDs can actually already be removed from builds by clicking the pencil icon next to the already added SSD. The build generator will automatically allocate the funds to other areas of the build.
However I would strongly encourage the purchase of an SSD from my personal experience even for a performance focused gaming build as the difference in everyday speed is huge and undeniable. Just something to consider.
Thanks for your interest and feedback,
