- Prefer not to pay everything at once? A 50% deposit is enough; the price is then 2% higher: deposit 158 303 Kč incl. VAT, and you pay the rest once the miner is on its way.
- The date reflects the factory production date plus a few days for shipping and customs.
- We set up the miner free of charge to mine into your wallet.
How the pre-order works
- You order online and receive an invoice – for the full amount or for a 50% deposit (price +2%).
- Once we receive payment, we order from the manufacturer.
- As soon as the miner has a tracking number, we let you know. With a deposit, you pay the rest at that point.
- You collect the miner in Prague, we ship it to you, or we connect it straight away on our hosting.

Description
Weight: 368.0 kg
Four Antminer S21+ Hyd hydro miners (395 TH/s each, 1,580 TH/s in total) in a Bitmain ANTRACK V1 rack. The rack is designed for 4 water-cooled Antminers of the S19 Hyd. and S21 Hyd. series with a total load of up to 24 kW – this set uses 23.7 kW of it.
What's in the set
Why they belong together
- Power draw: 4 × 5,925 W = 23.7 kW, i.e. below the rack's 24 kW limit.
- Form factor: the Antminer S21+ Hyd is a standard hydro Antminer (neither 2U nor 3U), made exactly for the ANTRACK slots.
- The rack runs on a three-phase 380–415 V supply (80 A input current) and needs a water flow of 32–40 l/min with antifreeze; we will design heat rejection from the circuit (dry cooler or heat exchanger) to suit the installation site.
What we do for you
- We fit the miners into the rack and connect the water and electrical lines.
- We test the whole rack in operation.
- We configure the pool of your choice (you provide the wallet address).
- We ship the rack on a pallet within the Czech Republic and the EU; the pallet shipping cost is shown at checkout.
Delivery
The ANTRACK rack is made to order; we confirm the delivery date after you place your order. The miners are in stock at our supplier in Hong Kong.
Warranty
The miners and all other components carry the same warranty as when bought separately – 24 months. Claims and servicing are handled directly in Prague at our ASIC miner service centre.
Set price
The set price is the sum of the current component prices less 2% (rounded up to …99 Kč). Compared with buying separately, you save 6 296 Kč. If the price of any component changes, we recalculate the set price.
