The only presets for making a slimmed OS are the Blackviper Services presets. Besides that, everything is manual so you can trim it down to your specific needs. Under "Component Removal", the options in green are considered "safe" to remove...and there are quite a lot of them. You can also mount the image to a directory and manually remove things such as system files, etc. For example, I removed all the unnecessary fonts from my image...taking the Fonts folder down to a mere 46MB. Just experiment and see how far you can take it.
