Zephyr Unveils ITX-sized Sakura Blizzard RTX 4070 Graphics Card

No, it isn't. The SFF spec for addin cards is limited to half height(70mm), single slot(18mm) at generally 180mm long.

There are two form factors for PCI Express cards - standard height and low profile. These are the main AIC form factors, further specs are about double and triple slot plus some standardization around length.
SFF - as discussed in that long thread about the stupid NVidia thing - is not an official term. Today, SFF is usually more accommodating to standard (or slightly higher) height cards than long or extremely thick ones.

What, where, whose spec?

Incorrect. SFF is exclusively a half-height, or low-profile if you wish, spec. Full height cards, regardless of type, are the standard general spec.

Pick your industry leader. Acer, Dell, Foxconn, HP, Lenovo, ect., ect... ALL of them conform to the same standard. I know there is a technical spec for it somewhere, not going to go hunting for it. The onus isn't on me as the evidence is all over the place.

tl;dr - there is no spec for SFF.

Btw, if you remember the initial name for SFF was Shuttle Form Factor

While there may not be an official spec for SFF, the office machine manufacturers tend to hew to a common form factor of half height single slot PCI. The only reasonably current consumer GPU fitting this spec that I'm familiar with is the Radeon RX 6400, a Sapphire Pulse (that I had for a while) and a Powercolor one.

Dell used to place their Optiplex PCI slots so you could fit a HH DS card in there (could fit a few 1650 or 1050 Ti models) but apparently not any more, the x1 slot gets the DS space now. WTF? I recently deployed a SFF Dell (a Precision? damn don't remember) with an RTX A2000 in it so there are still some models with HH DS space in them.

Yes. I want that A2000.

The main concern is the height, which as you indicated, it is limited to half. Many of the SFFs at the office allow for dual slot GPUs as long as they're half height.

SFF =! low profile. the original Shuttle Form Factor cases used what we call ITX cards, full height, dual slot, 7.67 inches long.

Most of the PCs these manufacturers make with expansion slots today support dual slot cards too, low profile or not. They're not limited to single slot designs.

It's not written down anywhere. unlike ATX, or PCIe, SFF never had a concrete definition.

Yeah dell cheaped out and switched from a x4 to a x1 slot with a back to it, so no more GPUs (Cmon dell, just put the x16 slot as slot 1, its not hard!). The precisions are different though, they still had the x16 up top, although I think the current model revised this. I really do like that case's form factor though. Carved one out to support normal ITX boards for my media PC.

Except that it's been around since the 90's. But whatever..
