Specs:
CPU: AMD EPYC 7262 — 8 Core / 16 Thread | 128MB L3 Cache
Motherboard: Supermicro H12SSL-I — Server ATX | PCIe 4.0 | IPMI
RAM: 256GB DDR4 3200MHz ECC RDIMM — NEMIX 8x32GB ($2,990 new on Amazon)
Storage: Solidigm P41 Plus 2TB NVMe PCIe 4.0 M.2
PSU: Super Flower Leadex Platinum 1600W — 80+ Platinum | 10 Year Warranty

GPUs — 96GB Total VRAM:

NVIDIA RTX 3090 Founders Edition 24GB
EVGA RTX 3090 XC3 Ultra Gaming 24GB
ZOTAC RTX 3090 Trinity 24GB
ZOTAC RTX 3090 Trinity OC 24GB

I also have 4 GPU risers PCIe4 (~$200), a GPU open rack with multiple fans, and an ARCTIC Freezer 4U-SP5 (~$50).

The 3090 Founder Edition was originally used for gaming and then switched to LLM Inference.
The 3 other GPUs are from Newegg and are only used for AI Inference. No mining or 24/7 operations. The whole server was used sporadically, mostly to test out local LLMs like GPT-OSS or Qwen. Selling because I mostly use cloud models nowadays.

The FE and EVGA have some metal fins added to dissipate more heat, but the GPUs were never opened or repasted.

Item Price Priority
Server+GPUs $6000 Preferred
4 x RTX 3090 $4000 Preferred as a 4 x bundle
Server Only (CPU+Memory+Mobo+NVMe+PSU+Cooler) $2500 If GPUs have already been sold
NVIDIA RTX 3090 Founders Edition $1200 If I split the GPUs
EVGA RTX 3090 XC3 Ultra Gaming 24GB $1100 If I split the GPUs
ZOTAC RTX 3090 Trinity 24GB $1000 If I split the GPUs
ZOTAC RTX 3090 Trinity OC 24GB $1050 If I split the GPUs

Prefer local only; I can meet anywhere within the San Francisco Bay Area. Cash, PayPal, or QuickBooks Payment (bank transfer with Invoice + extra fees)
I might be open to trading it for a DGX Spark + Cash difference (negotiable)

For local AI enthusiast:
If you are interested, I also included some benchmarks trying to make a summary of a 98-page book at a 128k context window

GPT-OSS:120B - Text 95 t/s, prompt 2340 t/s
qwen3.6:35b - Text 114 t/s, prompt 4325 t/s
gemma4:31b - Text 29 t/s, prompt 1174 t/s

[PC][US-CA]LLM inference Epyc server 4 x 3090

Over the last 2 years I put together a server for local LLM inference and so far it served me well. Unfortunately I’m not using it much and I’m trying to sell it to someone that can leverage more than me local models. This rig never did crypto mining, just local LLM inference with ollama.
I can sell it in the SF Bay Area but can also extend to Los Angeles.

Specs:
CPU: AMD EPYC 7262 — 8 Core / 16 Thread | 128MB L3 Cache
Motherboard: Supermicro H12SSL-I — Server ATX | PCIe 4.0 | IPMI
RAM: 256GB DDR4 3200MHz ECC RDIMM — NEMIX 8x32GB ($2,990 new on Amazon)
Storage: Solidigm P41 Plus 2TB NVMe PCIe 4.0 M.2
PSU: Super Flower Leadex Platinum 1600W — 80+ Platinum | 10 Year Warranty

GPUs — 96GB Total VRAM:

NVIDIA RTX 3090 Founders Edition 24GB
EVGA RTX 3090 XC3 Ultra Gaming 24GB
ZOTAC RTX 3090 Trinity 24GB
ZOTAC RTX 3090 Trinity OC 24GB

I also have 4 GPU risers pcie4 , a GPU open rack, and an artic CPU cooler.

I’m not 100% sure now how the pricing is now that there are memory, disk and GPUs shortages, I’m trying to get a vibe check on it. I’m also open to sell just the 4x gpu bundle if that makes it more appealing but maybe there is a market for a ready to use server.

Current pricing on buy new or refurbished was estimated almost at $9000 but I wonder if the real pricing is much lower in second hand resale.

What would be an appropriate color scheme for Embergard ?

I noticed that the new city of ash booklet showcased the heraldry of Embergard and in addition the regular transfer sheet has the same icon under the “miscellaneous” section. My understanding in the lore is that there few freeguild shock-troops there rebuilding the defenses together with stormcast from the Hallowed knights.
What would be a potential color scheme for the freeguild troops stationed over there ?

EDIT: there is a chance that the alternate box color scheme on the freeguild Grenadiers is in fact Embergard and not Graywater Fastness

EDIT2: I think I found the color scheme on page 42 of the City of Ash handbook. There is an image of the Battered Barricade relic with a Steelhelm skeleton wearing Embergard colors. Yellow coat, gray undercoat, red shield with light gray emblem. Very similar to the new Grenadiers alt color scheme. Not sure if it is going to be canon but at least there is an official GW art of it now.
