Contenitore 40 ft Raffreddato ad Aria 1.2 MW
Enterprise-grade platform, assembled and tested in the EU.
40 ft Air-Cooled Mining Container — 1.2 MW, Ready in Prague
A finished, factory-tested mining container sitting in our Prague yard right now. Skip the 25–30 day China build and 4–6 weeks of ocean freight — reserve it, inspect it powered up, and drive it out the next day.
Energy-ready, the day you collect it
This is a complete, plug-and-play 40 ft High-Cube container engineered for dense air-cooled mining in hot climates. It arrives fully wired and factory-tested, with the transformer feed, distribution, cooling and monitoring already built in. You bring the miners and the power — it does the rest. Because the unit is physically in Prague, there is no production queue and no shipping wait: the most expensive thing in mining is downtime, and this removes weeks of it.
Cooling that holds full hashrate in the heat
Negative-pressure exhaust array
Heavy-duty fans (16 × 1.1 kW, ~39,000 m³/h each) pull filtered air straight across the machines — the proven layout for high-density air cooling, sized for the full 1.2 MW load.
Water-curtain pre-cooling
A front wet-wall drops intake-air temperature several degrees on the hottest days. At a 34–40 °C ambient that is the difference between thermal throttling and sustained full hashrate.
Isolated hot / cold aisle
Partitioned sides keep cool intake and hot exhaust from ever mixing, configured for the specific miner you run.
CCTV & environmental sensors
Internal and external cameras plus temperature and humidity monitoring give you 24/7 remote eyes on the site.

How many miners it holds
With ~380 physical slots, the 1.2 MW supply is the practical limit at Antminer S21-class power draw — not the rack. Approximate counts per container:
| Model | Hashrate | Efficiency | Power | Max @ 1.2 MW | Recommended* |
|---|---|---|---|---|---|
| Antminer S21 Pro | 234 TH/s | 15.0 J/TH | 3,510 W | ~341 | ~285 |
| Antminer S21 XP | 270 TH/s | 13.5 J/TH | 3,645 W | ~329 | ~274 |
| Antminer S21+ | 235 TH/s | 16.5 J/TH | 3,878 W | ~309 | ~258 |
Ship miners with the container
We stock the latest Antminer S21 series and can dispatch them with your container. Integrated PSU included, 12-month warranty, bulk pricing at container scale.
In Prague, not in transit
- No 25–30 day China production — the unit already exists; the queue is behind you.
- No 4–6 week ocean freight — skip the ship, the port and the customs wait.
- Inspect before you pay the balance — see it powered up in our yard before committing.
- EU-based supplier — reachable, accountable, and easy to coordinate with.
- Collect the next day — arrange your transport, or we'll help line it up.

Load it and go, with handover notes and commissioning guidance.
FAQ
Is it really collectable the next day?
Yes — it's a finished, factory-tested unit in our Prague yard. Once your deposit clears we schedule collection for the following day. The roof fans and water curtain are fitted during a short 1–2 day commissioning at your site.
What does it cost?
Container and hardware pricing tracks the crypto market and moves daily, so we lock your price the moment a deposit is received. Message us for today's figure.
How many miners does it hold?
~380 physical slots; at S21-class power the 1.2 MW supply is the limit — roughly 258–341 machines depending on the model. We size it to whatever you run.
Can I add miners to the order?
Yes. S21 Pro, S21 XP and S21+ are in stock and can ship with the container. PSU included, 12-month warranty, bulk pricing at scale.
What about transport and power hook-up?
Collection is from Prague; we can recommend hauliers and help coordinate loading. Grid connection and the medium-voltage supply are arranged on your site.
The questions buyers ask us most often before ordering a server.
How long does it take?
Machines built from components we hold ship quickly; anything requiring a specific GPU generation depends on supply. We give you a date before you pay, and if it moves we tell you rather than letting you find out.
Can the configuration be changed before you build it?
Almost always. GPUs, memory, storage and cooling are chosen per order, and the listed configuration is a starting point rather than a fixed package. If you need more VRAM, faster storage or a different cooling approach, say so before you order and we will quote the change.
Can I collect the server in person?
You can. Our warehouse is in Prague, and collection in person is welcome — most people who come use the visit to go through the machine with our engineer and ask the questions that are awkward over email. For orders within the Czech Republic we also try to deliver personally and walk you through the setup on site.
Can I talk to someone who actually understands the workload?
Yes. We have an engineer who works on AI systems specifically, not a general sales desk. If your question is about batch sizes, quantisation, interconnect or where your bottleneck will be, ask it — that conversation usually changes the configuration for the better.
Which model can I run on this configuration?
Yes. Every machine is assembled, burn-in tested and benchmarked on real AI workloads before it ships, and it leaves us with an LLM already installed and running. You plug it in, connect it to your network and start work — the only decision left is which project it runs first.
How do you test a server before shipping?
We run it against actual AI workloads rather than synthetic scores: inference throughput, sustained load behaviour and thermals under continuous operation. You get the benchmark results with the machine, so the performance you were promised is the performance you can verify on day one.
Is the server ready to run when it arrives?
Yes. Every machine is assembled, burn-in tested and benchmarked on real AI workloads before it ships, and it leaves us with an LLM already installed and running. You plug it in, connect it to your network and start work — the only decision left is which project it runs first.
Ships from our EU warehouse. Heavy items may require freight arrangement — contact us for a shipping quote and lead time. 2-year limited warranty with advanced RMA support; extended warranty available.
Not exactly what you need?
Tell us your workload and we'll spec this platform around it — GPUs, memory, storage and cooling matched to what you actually run.
