If you looking for something different to house all you media equipment in, and have a fair bit of spare cash then you may want to check out the Horgan Becket Media Cart.
The Horgan Becket Media Cart is hand crafted to your exact specifications, so you should be able to have one designed to house your Xbox, PS3 and Nintendo Wii, plus your giant HDTV.
Inspired by the robust spirit of the American industrial era and by the nature of the parts that were created, HB Media Cart is an expressive alternative to universal wall mounts and concealed flat screen TV furniture. Its basic character is open and bold, yet its presence is a surprisingly polite visual event. Its unique tactile detailing stages a lively interaction with its surrounding space and the media components within.
If you want one, the Horgan Becket Media Cart starts at about $12,000, so I suspect a customized version is going to be slightly more.
