wschwartz,

Would you care to post a link to some web pages describing the gadgets you bought? I might be able to use one, too...

With regard to your placement of the receiver etc. inside the built-in "entertainment center," my $.02 of advice are: Be careful not to overheat your receivers/amps by operating it at high levels for a prolonged time period in an enclosed environment. I also place all my electronics inside the built-in entertainment shelves, but I always keep the front door open when they are in use...
