[W] Single-Socket AMD EPYC SP3 Motherboard (ATX/E-ATX) for 7002/Rome - US-CO

[US-CO] Looking to source a reliable single-socket SP3 motherboard to complete a personal AI and gaming server build.

I already own an open/un-fused AMD EPYC 7642 CPU, a matching 8x32GB (256GB total) NEMIX DDR4 ECC RDIMM memory kit, and two NVIDIA Tesla T4 cards. I am mounting this setup inside a Rosewill 4U rackmount chassis.

**Strict Exclusions:**

* NO Supermicro boards (not looking to deal with proprietary vendor/firmware locking hoops).

* NO flashed Revision 1.0 to 3.0 Gigabyte boards (due to known SlimSAS/Mini-SATA NVMe trace multiplexing bugs).

* NO dropshippers or broker stock photos.

**Target Boards (Ranked by Preference):**

1. **ASRock Rack ROMED8-2T** (Highly preferred for standard ATX form factor and 7 native physical PCIe x16 Gen4 slots).

2. **Tyan Tomcat SX S8030** (Models: `S8030GM2NE` or `S8030GM4NE-2T`). Clean ATX layout that fits my Rosewill standoffs, offering 5 native physical x16 Gen4 slots.

3. **Gigabyte MZ32-AR0 (True Rev 3.0 Only)**. If offering this E-ATX board, please verify that the physical silk-screen print on the PCB corner explicitly says "Rev 3.0".

**Requirements & Rules:**

* Must include the original matching metal rear I/O shield/backplate (critical for holding air pressure in my custom internal fan-wall wind tunnel configuration).

* Pins inside the SP3 socket must be 100% flawless with zero bends.

* Per subreddit community rules, **you must comment on this thread before sending a PM.** Please include a time-stamped photo link showing your username and today's date next to the motherboard traces.

**Payment:** PayPal Goods & Services ready depending on model, condition, and shipping tracking.
