Built to spec · validated under full load

Enterprise AI workstations & servers, built without compromise.

Multi-GPU Blackwell systems, hundreds of gigabytes of memory, and storage arrays in the tens of terabytes — for AI training and inference, rendering, and serious compute. If your workload eats GPUs, we build the machine that feeds it. Spec'd, assembled, and validated under full load in Fairport, NY.

What we build

These are the builds that never fit a configurator dropdown. We spec each one to the workload, source the parts, assemble by hand, and prove it under sustained load before it ships.

Multi-GPU training rigs

Two, four, and more Blackwell GPUs in one chassis, on a platform with the PCIe lanes and power to drive every card — for training and fine-tuning your own models.

AI inference servers

Built to serve models in production: the GPU memory to hold them, the throughput to answer fast, and the reliability to run around the clock.

Large-memory workstations

Hundreds of gigabytes of ECC memory, into the terabyte range, for in-memory datasets, huge scenes, and memory-bound pipelines that choke a normal PC.

Storage & RAID arrays

Fast NVMe scratch plus large RAID arrays for datasets, checkpoints, and archives — sized to the data your jobs actually move, with redundancy where it counts.

Render & simulation

GPU-dense machines for rendering, engineering, and scientific simulation — the same multi-GPU horsepower, pointed at a different kind of heavy lifting.

Any GPU-dense compute

If the bottleneck is GPUs, memory, or storage bandwidth, we'll build for it — AI, rendering, simulation, even GPU proof-of-work compute. You want it, we build it.

No spec is off the table

We build on workstation- and server-class platforms, so the ceiling is a lot higher than a desktop's. Here's the range we work in — the exact parts get chosen for your workload.

Graphics
Blackwell-series GPUs, single or multi-GPU — high-VRAM cards for the largest models, scaled across the chassis with the power and cooling to sustain them.
Processor
High-core-count workstation & server CPUs — Threadripper PRO, EPYC, and Xeon class, chosen as much for PCIe lanes and memory bandwidth as for cores.
Memory
Registered ECC, hundreds of GB into the TB range — multi-channel, sized to keep the GPUs and the dataset fed without spilling.
Storage
NVMe scratch + large RAID arrays — fast working storage for active jobs, bulk capacity for datasets and checkpoints, redundancy where the data can't be lost.
Power & cooling
The hard part, done right — high-wattage and redundant power options, and the airflow and thermal headroom to run every component at 100% for hours.
Form factor
Tower workstation or rackmount server — built for under a desk or for a rack, and quiet enough for wherever it has to live.

Built and proven like infrastructure

A machine this expensive shouldn't first run hot on your deadline. Every high-end build is hand-assembled, firmware-updated, and stress-tested under sustained full load before it leaves the shop — and you deal with the people who built it, not a reseller.

High-end build questions

How many GPUs can you put in one system?
Single-GPU through multi-GPU on the Blackwell series — two, four, and up — with the platform, PCIe lanes, power delivery, and cooling to actually sustain them at full load. The right number depends on your models and budget, which is what we work out on a build consultation.
How much RAM and storage can these builds have?
On the right platform, hundreds of gigabytes of ECC memory into the terabyte range, and storage from fast NVMe scratch up to large RAID arrays for datasets, checkpoints, and archives. We size memory and storage to the data your workload actually moves.
Do you build AI servers, or just workstations?
Both — a quiet tower workstation under a desk, or a rackmount server for a closet or data room. Same engineering either way. Tell us where it has to live and how it has to run, and we build to that.
What workloads are these built for?
AI training and inference first, then GPU rendering, scientific and engineering simulation, and other GPU-dense compute — even GPU proof-of-work, if that's your thing. If the bottleneck is GPUs, memory, or storage bandwidth, we build the machine that clears it.
How do I get a quote for a high-end build?
These are spec'd one at a time, so they start with a conversation, not a configurator. Email sales@jncs.com or call (585) 388-8780 with your workload, budget, and where it needs to run, and we'll put together a build and a quote. No obligation.
How are these validated, and what support do they include?
Every high-end build is hand-assembled, firmware-updated, and stress-tested under sustained full load before it ships. They carry a 3-year warranty and lifetime support, and you talk directly to the people who built and validated the machine. Local to Rochester? Pick it up at the shop.

Tell us the workload. We'll build the machine.

Bring us your models, your datasets, or your toughest compute job — and your budget and where it has to run — and we'll spec, build, and validate the system for it. Free consultation, no obligation, and a real builder on the other end.
