FAQ
Quick Answers Before You Buy
Is 32 GB of GPU memory enough to start with?
For the listing's stated audience — LLM apps, RAG, agents, and model experiments — yes, comfortably. When your models outgrow it, the 48 GB and 96 GB rungs are on this same listing.
Does it come with an AI agent framework pre-installed?
Not by default. The OpenClaw enterprise AI agent framework is available as an optional add-on, configured at order time — once added, you can build and run agentic workflows with no framework setup.
Can I get it with Windows?
It ships with Ubuntu pre-installed; Windows is available — request a quote from the listing.
How do I upgrade later?
GPU rungs to 96 GB, an AMD Ryzen 9950X3D CPU alternative, and memory to 192 GB across 4 DIMM slots — all within this listing family.
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. Build to Order — custom built and stress-tested after purchase.

The ABS Zaurion Ruby ZRE4565P-RP4500 is an entry AI developer workstation built for teams and professionals creating LLM apps, RAG pipelines, and AI agents, pairing an AMD EPYC 4565P with an NVIDIA RTX Pro 4500 Blackwell 32GB GPU, 128GB ECC DDR5 memory, dual 2TB NVMe SSDs, and Ubuntu with OpenClaw pre-installed.
Recommended For
AI developers who want a Linux workstation for local LLM app building, RAG pipelines, and agent workflows, and need more VRAM headroom than consumer GPUs typically offer without moving to a rack server.
Data science and applied ML teams running repeated local experiments, inference jobs, and preprocessing steps that benefit from ECC memory, 128GB system RAM, and workstation-style reliability over a gaming-first build.
Small teams deploying edge or office-side inference where lower power draw, pro drivers, and a desktop form factor matter more than chasing the fastest tokens-per-second from larger consumer cards.
Engineering, visualization, or simulation users who mix AI workloads with professional graphics software and prefer a single workstation GPU with certified workstation positioning instead of a consumer graphics card.
