FWIW, there are four 2.5" bays in the front that are connected to the SAS expander. The two 2.5" slots in the rear are meant to be used as OS disks presumably as they are the only ones not on the SAS expander.
The specs say the 12 x 3.5 are SAS or SATA, the 4x front are 2.5" SATA, and the rear 2x 2.5" are sata. Where are you seeing the 4x 2.5" front are SAS?
Per this: QuantaGrid SD1Q-1ULH | 1U Storage Server | QCT.io
I could very well be wrong about that but page 10 of the Users manual says:
"The system features storage drive cage supporting up to 4x 2.5” SAS/SATA HDD/SSD (7mm) on front bottom chassis."
The manual is pretty short on details though so it might be a typo or an error. I'll have to wait for friday to verify that they are actually SAS but I remember the front 2.5" cages being electrically outfitted for SAS at least. It might be moot though as I don't recall there being many 7mm height SAS3 2.5" drives at any rate.

It's a two-part affair, the CPU board (with BMC, serial, and VGA) and the breakout board that has mezzanine connectors, power, and dual integrated SFP+ ports.
It's actually laid out fairly well in the sales brochure longbowch linked to in this post:

7mm SAS SSD are hard to find. Seagate was one of the last to make 7mm SAS.
New SAS drive models are 15mm.
They are OCP 2.0 Mezz cards. They are a bit hard to find as the market has moved to OCP 3.0.
Not really and cheap too: Quanta QS-3008-8i-IR-V2 QS 3008 8 Port 12Gbps Storage Mezz Card LSI SAS3008 | eBay
By hard to find, I meant manufacturers are not making new versions of OCP 2.0 cards.
i'm really tempted by this machine... a few questions for those more knowledgeable here...
I have a Dell 4210 42U rack that has a hair short of 29" between the front rails to the rear rails (inside the rack). The rack itself has more depth, between the front and rear doors, so that's just rail to rail distance. There's enough space for 39" from front door to rear door. How do these rails mount? will it stick out pass the rear rails? Is it going to fit in my Dell 4210 rack? The dimensions are:
Height 78.7" (1999mm)
Width 23.94" (608mm)
Depth 39.93" (999mm)
Weight 307lbs (170kg)
Max. load 2,000lbs (907kg)
Would also like to hear some opinions from anyone who bought this and have it on hand. How are you liking it so far? pros? cons?

So, I ordered a few of these to play with, 2 of the 4 had physical damage and can't be racked, waiting on the vendor for replacement. Shipping box and packaging was fine, so I assume they were damaged when removed and not noticed when they packed them up for shipment.
They came with both mezz slots filled, one with a 2x 10gb sfp and one with a 3008 LSI mezz card. I replaced the LSI mezz with a 3108 series mezz, easy swap.
I was concerned if these would be serviceable (replace a HDD) without shutting them down, and to my surprise, they are! You can pull the front of the system out that has the HDD's in them while the unit is running, which allows you to service/swap HDD's, without taking the unit down or out of service...risky but doable.
The 12x 3.5" are SAS only, the 4x front 2.5" are SATA or SAS, and the rear 2x 2.5" are SATA only. The 3008/3108 LSI raid supports the 12x 3.5" HDD's and the front 4x 2.5" SSD's. The rear 2.5" are NOT supported by the LSI raid mezz. There is a PCH bios setting for these rear slots. Not sure if they are fake raid or what, but I haven't found anywhere to setup raid on the rear 2x 2.5" SSD's yet.

It looks like these were part of some large CEPH or other distributed storage setup at some large cloud provider, they have labels on them with various StorageX notations, storage127, storage4, etc.

This chassis from QCT Quanta is popular with storage providers due to its density per rack 'U'. I work for a system integrator, one of our customers uses this chassis with a different QCT system board. Unfortunately, due to its size and design it does not ship well individually. We ship four nodes, servers, per order, stack and bind them on a pallet. No shipping issues since we started palleting them. The StorageX could be reference to Data Dynamics file management solution:
StorageX – Data Dynamics, Inc
One of our customers uses this chassis. They have not had any issues with the rack rails mounting and working properly in enterprise racks like the one you mention in your post. They include a cable management arm which has had mounting issues with racks that have limited room between the back rail mount and the back door.
Do you happen to know of the part # of the BBU that works with the 3108 mezz card? Can't find it on the FRU or datasheet.
Thanks for your insight on the rack mounting. So, you are saying it should fit. Based on the measurements, am I right in assuming it would stick out a few inches pass the rear rails?
