Anybody(rich people) can throw money at equipment to fill up a room, but may have to spend tonnes more and settle for less than stellar quality then if the room was designed for it's purpose.
Nothing worse then sitting down to watch a movie and you can't hear the dialogue properly or the delay to the rear speakers is set wrong.
A proper theater room built from the ground up is nowhere near the same as a regular room in a house.
Everything from building materials, to HVAC, to electrical, to the shape of the room is different.
Now, if he can't tell the difference between a HTIB or a proper system, or maybe doesn't really care and it's all just for eye candy then it's a different story.
This. If I had private jet money and was looking for the ultimate in HT my first step would be constructing a dedicated addition to my home. Multiple huge subwoofers and amplifiers are going to require multiple high-amperage dedicated circuits. High powered amps and projector(s) are going to require an additional AC unit (or more than one depending on the size of the room and its level of isolation from the rest of the house). If high output at ultra-low frequencies is desired you'll want the room isolated from the rest of the house so that you are't rattling things off of the shelves and/or disturbing other people when watching movies.
Hitting meaningful SPL at 5hz is going to require something like the Eminent Tech TRW-17 rotary subwoofer in addition to normal subwoofers covering the traditional sub range, and that requires an IB setup with its own dedicated space.
If cost is no object there's no reason to limit yourself to plain old 7.x.4 surround when Trinnov and JBL Synthesis processors exist that can handle 32 or more channels.
When it comes to video he may want multiple projectors to get the best 3D and HDR performance, or may want to go with a direct-LED video wall. There are even home versions of commercial projectors, some requiring dedicated liquid cooling setups that bring their own room, electrical, and HVAC requirements.
JTR and Seaton make excellent products, especially for the bang-for-the-buck, but the JBL Synthesis and pro audio lines are also worth a look (I'd love JBL M2s all around in a dream theater scenario) as are professional theater speakers from QSC and Klipsch, or options from Procella, James Loudpseaker, PMC, Danley Sound Labs, or a variety of other options.
It comes down to how 'ultimate' and 'cost is no factor' he really wants to go, spending $50,000, $500,000, or $5,000,000 will all lead to very different design decisions. Regardless he'll want to sit down with a professional who will create a holistic design so that there are no weak links, who has the experience to know all of the little (and big) details and issues that need to be addressed so that there are no surprises, and who can create the proper documentation and long-term support plan that he'll need to enjoy the system for many years.
