This is a fun, and I enjoyed the "CRT Dude" video because I resonate with that need to understand :-). One of the things I learned during that era was that there were a lot of computer makers but relatively few factories in China that were making things to assemble them. Because it was simpler to take the sheet metal work that was already designed and being made for brand 'x' and then differentiate on the case molding and electronics, a lot of the mechanical components were "re-used" (the factory can make 1000 or 10,000 with the tooling and the more they make the easier to amortize the tooling costs so the cheaper they can offer them).
I suspect when a company spec'd out a new design and then got all the tooling done, unless they explicit language in their contract about selling stuff made with the same tooling to others, the factories could pitch "we will do the basic case with no NRE[1]" and that was a bargain. As a result a lot of things ended up being "magically" similar in those days.
[1] NRE = Non-Recoverable Engineering which is the cost label for the engineering work to build the jigs and tooling that the factory will use to make the parts you want. Example an injected molded switch cover might cost $10,000 in NRE to make the molds that can produce 10 switch covers each and be used up to a 10,000 times. Then if you make 10,000 switch covers, you have used the mold one 1000 times and used up 10% of its lifetime. Cost of the plastic plus $1,000 (the 1/10th of the cost of the mold) are the real cost of those switch covers.
No, they most emphatically were not. The early 3000 series, like the MIPS based DECstation and VAX based VAXstation, were based on Turbochannel[1], which was DEC's primary bus technology at the time. Later Alphas used PCI as their primary bus. There were Tubochannel to VME adapters, and PCI to VME adapters, but VME was never a primary bus used in alpha.
Before the PC era computers were mostly integrated in the keyboard (many 8-bit home computers), the monitor (Apple Lisa) or both (Commodore PET).
Then they became more or less flat boxes on the desktop. Early PC's were like that (the bulky version) but also early workstations like Sun's SPARCstation (the more elegant version). They were meant to put a monitor atop.
Over time the boxes got bigger and louder and the monitors got bigger which made this design impractical. Some people flipped the boxes, put them under their table and the tower was born. Not long and professionally made tower cases appeared.
Over time the bulky towers got smaller and we had Midi- and Mini-Towers on the PC side and things like the Sun Ultra 24 or the SGI O2 on the workstation side. These could be put on the table again but this time next to the monitor and not below it.
But they were really, really good. An Indigo² Solid Impact R4400SC 250 was my main PC from 1998 until I left the US in late 2003. Built like a tank. Incredibly smooth in operation. Rang rings around my iMac G4, which ended up just sitting on top of the SGI's Trinitron running iTunes. I loved that machine, and I will go retrieve it in a few months.
Now the Fuel, of the final MIPS generation, was hot garbage. Early-2000s PC crap plus SGI does not equal awesome. Fast, but flaky, stuttery, and with too many graphical artifacts for the price. Maybe the V12 was better than the V10. I don't care to find out.
It makes sense, if one considers them the evolution of the Apple II and the IBM PC.
The IBM had the motherboard on the left, along with the expansion cards, and the drives and power supply on the right. The AT continued this.
Clones wanted mostly compatible cases, and motherboards wanted to be mostly compatible with IBM cases and clone cases.
Then we had Amigas like the Amiga 3000, which had a similar layout but a riser to take horizontal expansion cards.
While some more bespoke PCs had vertical risers, most PC cases in the early to mid '90s were large. It was the machines we paid a bit more for that made being smaller in to something a bit premium.
While taking apart my Amiga 3000 is a bit of work, the design is absolutely wonderful, and more than once I thought about the design of it compared with later machines like the Sun Ultra 5, the Motorola StarMax (PowerPC Mac clone) and others.
...and Turbochannel was originally the bus for the MIPS R3000-based Ultrix workstations; the Alpha firmware needed to be able to interpret MIPS machine code to speak to TC expansion cards.
Somewhere, I have a Turbochannel FDDI card taken from an AlphaStation 3000-an obsolete I/O adapter for a forgotten network protocol, running on a defunct CPU, with firmware written in the native language of an even more defunct CPU.
The early 90s were the era of (1) Pentium (2) PCI (3) multiplatform Windows NT. Most vendors switched to desktop/deskside designs based on PC bus and PC components, it would be more cost competitive (volume economics) and could run NT/Alpha, NT/MIPS, NT/PowerPC if the market went that way.
Hmm...makes me wonder if a PA-RISC HP 9000 712 is a better NeXTStation than a NeXTStation is today, in terms of longevity, supportability, performance, etc.
I guess its missing the DSP and fancy printer interface of the NS, maybe the overall sound quality.
Something to keep in mind is available software for NeXT computers versus for platforms that NeXTstep got ported to (x86, PA-RISC, SPARC). Many later software written for NeXTstep and its successor OPENSTEP had “fat binaries,” meaning that they contained machine code for multiple platforms. However, there are noticeable software packages released before NeXT’s transition away from their own hardware that only have a 68k binary. I believe WordPerfect, Lotus Improv, and Adobe Illustrator fall in this latter category.
Unlikely to be better in supportability terms, since we are talking about a 30 year old OS on 30 year old hardware that wasnt the primary development target.
However, in terms of build quality, I would take the old HP 9000s over NeXT cube any day. Those old HPs were engineering workstations built by an HP that at the time still cared about engineering.
Jobs and the NeXT crew built beautiful things, but at that time they didnt have the decades of experience that HP did. (I'd say the same about old RS/6000s by the way.)
A trivial example is how when you open up the back, engineering workstations did not slice up your hands on stamped metal frames and risers. Whereas PCs of the time generally did. (Compaq was a notable exception, but you paid a price premium for it.)

If you could install IRIX on junk commodity hardware no one would have a reason to pay SGI $100k for one of theirs.

Early Alphastations were assuredly not VME! They were DEC's own Turbochannel.

I own a NeXT Cube and three NeXTstations.
