I remember all the 2013 Mac Pro users that tried to expand with everything they needed via Thunderbolt. It was some of the worst cable/desk clutter scenarios I've ever seen. It's also much more expensive to go that route. I'd want to use what I already have and connect it to PCIe slots internally. The trashcan MP still got too hot even though everything but the AMD FirePro cards were external.
Here's some of prices Sonnet is asking for external PCIe enclosures. Add to that the cost of certified TH4 cables.

Yeah, no doubt. Some devices might also require short cables which would only make cable management an even worst nightmare. The Trash MP had a form-over-function design imho, but then again I'm not the target audience so I am not even sure I have a say in that, I considered buying one at the time but built a Hackintosh instead.
As far as price, I am not sure whether that's still true or not if you take into account the initial cost of a current MP VS a Mac Studio. Also, I suspect that if one is in this high-end bracket you wouldn't go adapting pcie devices to be external, that's sounds very risky, you would just buy the external versions from the same brands, which had no alternative to stay on the Mac market during the trash can era other than making things external.
The Pro industry didn't stop when Apple stopped making computers with PCIe, it just frustrated the heck out of it.
Thanks for the labelling for the rest of us. So these are PCIe x1 audio cards (some with daughter cards, which is a good use case for a double height x8 slot). I suppose that, individually, any one of these cards could fit in a Thunderbolt enclosure. But there's the sheer number of them. One enclosure may be OK; but four or five of them, each enclosure with its own discrete power supply? Chained, with added latency? Or with a dedicated Thunderbolt port for each? There may not be enough ports to begin with.
I'm no audio user, and to each his own. But if I needed so many cards to work with, I'd want them in a single chassis. If that chassis costs 3000 extra, so be it—especially if it passes as work expenses.
No prob.
Well, again, putting that particular list of gear on enclosures sounds like a terrible idea to me VS buying the external versions... Dealing with a power supply for each, risking compatibility problems, etc... Pro Audio guys tend to stick to what works and want no problems, ever, if that means sticking with an OS from 4 years ago that's what they will do, so it's hard to imagine these folks using that external enclosure route.
Regarding the number I have no idea tbh, surely there's a limit for chaining, bandwidth, or Ports.
Consider that if funds aren't a big problem for you then you likely max out either approach, internal or external, meaning if I have 6 pcie lanes available I will plan for it specifically when I buy things and I will max that out but that doesn't necessarily mean I can have the exact same amount of stuff externally.. the same way I can't shove 15 external devices internally with only 6 pcie lanes if I had planned for an external approach instead... So this can kind of works both ways.
