There are many people who say home theater furniture looks all the same. Even if you don't agree, modifying and hacking an entertainment media furniture piece can help create a unique configuration...the only limit is your budget and your ingenuity as showcased by these examples below...
Mary from Guelph, Ontario, Canada, and her husband were trying to find the perfect entertainment center for their home. They decided to use a long wall in their house, but they wanted to keep things low, like a custom credenza because there were some windows on that wall. They weren't able to find one long enough in stores. Instead of going completely custom, they decided to combine two IKEA Besta shelves with a Billy bookcase to come up with their own made to order entertainment center.
The two Besta shelves are located on each side of the entertainment center. They are combined by using some Billy bookcase shelves as a middle joiner. The whole thing was made to look like a complete credenza thanks to some leftover wood from their flooring. This allowed them to make a sort of table top for the entertainment center, making it seamless.
On top of having enough space for all of their home entertainment equipment, it also has a lot of storage space. Since it's quite long, they can stash quite a few things before it starts to look cluttered. Their only regret is when they sell the house, they'll probably have to include the entertainment center since it will be too long for usual living rooms.

A few strategically placed LED lights would give long and low media credenzas a warm ambient glow. IKEA's Dioder is a cheap and easy option. Dioders give a decent amount of lighting, primarily as secondary mood lighting, while also being very simple to mount.
