Is it possible to buy sony HTPC case?

Try something by Antec.

Rather than conjecture, let me provide you with some resources so you can make an informed decision. If you want state-of-the-art type stuff, check this out, and get your wallet out, too (if you're willing to "pop" for Sony, this shouldn't hurt too much ):

and here's a review of that product with a good resource link to all HTPC:

My fav:

Happy researching!

In looking through my archives, I came across this one, as well, which looks very close to the Sony, but not as tall. Don't have a review:
