Lærke PC Builder turns any product page into a guided custom-PC configurator. Shoppers pick each component from your own catalogue, one slot at a time, and only see parts compatible with their earlier choices. You decide how each part is priced and which combinations are allowed, so every build is one you can fulfil. Finished builds go to the cart as a single line at your price, with the components kept together. It installs as a theme app block, with no theme code to edit.
