Module 07 · FAQ
Quick Answers Before You Buy
Can it run large language models locally?
Yes — the RTX 5090's 32 GB of GDDR7 comfortably serves mid-size open-weight models; the optional Qwen 3.5 27B (or higher) package ships pre-configured for private on-prem inference, and the optional OpenClaw framework adds agentic AI out of the box.
Why Threadripper PRO instead of a desktop CPU?
The liquid-cooled 24-core Threadripper PRO 9965WX on the AMD WRX90 platform brings workstation-class parallelism, ECC Registered memory support, and the PCIe lanes that feed 7× PCIe x16 slots and dual PCIe 5.0 NVMe drives — desktop platforms can't.
How far can I expand it later?
8 DIMM slots take system memory up to 2 TB; 7× PCIe x16 slots (Gen5) accept future accelerators and NICs; and 4× 3.5″ internal bays add bulk storage — all inside the ASUS ExpertCenter Pro ET900A X9 chassis.
What operating system does it ship with?
Ubuntu comes pre-installed — the native home of CUDA, PyTorch, vLLM, and the open-source AI stack.
Is it eligible for government / public-sector purchasing?
It is TAA compliant and assembled in the USA, with compliance documents available for purchase review.
How is it supported?
1-year parts and labor limited warranty backed by ABS manufacturer support. As a Build to Order system, it is custom built and stress-tested after purchase.

This is a high-end tower AI workstation built for teams and professionals running local LLM inference, AI development, data science, HPC, and GPU-heavy rendering, with a 24-core AMD Ryzen Threadripper PRO 9965WX, ASUS RTX 5090 32GB, 128GB ECC DDR5, and Ubuntu in a workstation-class platform.
Recommended For
- Teams building or testing local AI workflows on-prem—such as RAG, agent frameworks, and single-GPU LLM serving—who want an Ubuntu workstation with ECC memory, 10GbE, and enough VRAM to run many 27B-class models locally without moving straight to rack servers.
- Studios or solo creators doing GPU-heavy rendering, AI-assisted video, and 3D content work at a fixed desk, where the value is high local throughput plus 32GB VRAM headroom for larger scenes, effects, and creator apps rather than portability.
- Engineering, simulation, and data science users who need a desktop workstation platform with Threadripper Pro-class CPU resources, ECC RDIMM support, multiple PCIe Gen5 slots, and dual 10GbE for storage-heavy or networked workflows.
- Developers who want a prebuilt workstation base for experimentation now and expansion later—adding storage, NIC-connected lab gear, or more PCIe devices—without starting from a consumer gaming tower.
