The ideal option is a headlamp, because it leaves your hands free, but you can also use a flashlight, your phone, or a desk lamp. Pro-tip: A movable light source will help you illuminate the nooks and crannies of your case.
You don't want to have to worry about blocking your only light source when you bend over the chassis. Build in a well-lit area with multiple light sources. Pro-tip: For assorted screws, we recommend magnetic hardware trays or trays with multiple small compartments such as empty egg cartons or vitamin containers. Without proper organization, these items can easily get mixed up.
You'll need a way to keep assorted screws, zip ties, cables, manuals, etc. Most components come with additional parts some optional, some required for installation in your build.
