Phanteks ships the Eclipse P200A in a brown cardboard box with an outlined image of the enclosure on the larger sides. There is very little extra information on the sides besides a few stickers, so I assume Phanteks will add a more prominent sticker to let resellers know if they are grabbing the Performance or RGB version for sale.
Two thick Styrofoam spacers hold the case in place, and a plastic bag protects the Eclipse P200A from scratches and fingerprints.
Besides the case, you get the usual set of zip ties and screws, but Phanteks also includes a bracket for vertical GPU installation, which is quite interesting for a $50 M-ATX chassis. A basic manual and warranty pamphlet round out the accessories of the Eclipse P200A Performance.
