This is a 4U rack case from SKB. It has brackets on both sides for screwing in equipment. The screws and receivers included are only those shown in the images. There are no functional problems, and there are no holes or cracks. There are some scratches, but I didn't see any major ones. I bought it new and used it only at home for several years. I will wrap it in bubble wrap for shipping. External dimensions: Depth: Approximately 56cm Width: Approximately 54cm Height: Approximately 24cm Internal dimensions: Depth: Approximately 40cm Width: Approximately 48.5cm Height: Approximately 17.8cm
