If you read the buyer reviews of that unit, numerous people say that it will not hold a standard depth AV receiver. Why would you design an audio rack that doesn't hold audio equipment?
I too, have been looking at cabinets. I guess you get what you pay for, as the higher end units are plenty deep without having to chop them up before you can use them. My wife and I have checked all kinds of furniture options. I have been watching all the junky furniture offerings on Craigslist and have not seen anything of note- cheapo TV stands, huge entertainment centers, and the ridiculous armoires. Funny how flat screen tvs obsoleted a whole line of furniture!
It's a tough one.
If you have a relative with wood skills, then this piece may work fine. Good luck!
