The wide variety of spaces on an entertainment center makes it perfect for storage of garage items. Over time, most garages become a disorganized collection of discarded junk, but an entertainment center can help make your garage organized and neat. Most entertainment centers don't have a back, which is not a problem when you place them against a garage wall.
An entertainment center in some cases can work very well as a room divider in place of beads/curtains or a new wall. If the entertainment center has a back, removing it creates storage space between two rooms that share a purpose. For instance, if you use it to divide the kitchen and dining room, the entertainment center can be a place to hold plates, silverware or even condiments.
As an offshoot to a room divider, consider the entertainment center as a way to divide a large bedroom between siblings. Teenagers especially like their privacy, and if the bedroom is large enough or the entertainment center small enough, you can fit it into a bedroom to give siblings, or any two people sharing a room, a sense of their own space. Divide the areas of the entertainment center equally and allow the two people to use it for clothing, books, collectibles or video games.
Very large entertainment centers, and especially the kind with doors attached, can be turned into small closets. With a few simple alterations, an entertainment center can become a place to store shirts, shoes, purses, ties, vests, sweaters and other items of apparel that don't take up much vertical space. Even those without doors can be turned into a small closet area if you can make the stacks neat and aesthetically appealing.
