The things under the black covers are 88-key MIDI controllers. Well, the one you see most of is a K2500XS. And while it still has a $9,999.95 sticker on it from Guitar Center, I bought it in 2003 for about $1100. A few of the Dolby pieces are worth something; the DP564 and DP569, for starters. However, there's very little aftermarket for them so they're worth substantially less than their MSRP. There are, however, two 480Ls and a TC 6000 in there. The RAID is not pictured, and was under $2k retail. The furthest left stack is a bunch of Lexicon PCM80s and 81s under some SSL X-Link MADI boxes. The furthest left thing is my super-bitchin' subwoofer with vestigial stuff from my father in law. For all I know it's worth more than the sub; it's a Mettler scale that will measure up to 50kg in 0.1g increments. But then, it's old enough to have a GPIB port.
