- Prefer not to pay everything at once? A 50% deposit is enough; the price is then 2% higher: deposit 50 438 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
Dimensions: 52 × 39 × 120 cmWeight: 69.0 kg
Antminer S21 XP 270 TH/s in the PC Praha double soundproof box for machines up to 5 kW. The box reduces noise by up to 47 dB – a miner at around 75 dB will sound roughly like a quiet household in the room (around 38 dB measured with an Antminer S19). Suitable for a flat, an office or a family house.
What's in the set
Why they belong together
- The Antminer S21 XP 270 TH/s draws 3,645 W, which is above the roughly 3.5 kW limit up to which we recommend the single 40 box. The double box is built for more powerful machines up to 5 kW, so it has headroom.
- Separate cold and hot zones, warm air exits vertically upwards and the miner stands on an anti-vibration mat.
- The heat (3.6 kW) can be ducted out of the room – we will be happy to offer you a duct connection.
What we do for you
- We install the miner in the box and prepare the interior fittings specifically for this model.
- We test the set in operation – temperatures, fan speeds and hashrate.
- We configure the pool of your choice (you provide the wallet address), or help you choose a pool.
- You can collect it in person in Prague 10, or we ship the set.
What you need at home
A socket or dedicated 230 V circuit rated for a continuous load of 3.6 kW (miner power supply 220–277 V). The set's dimensions are determined by the box: 52 × 39 × 120 cm.
Warranty
The miner and the other components carry the same warranty as when bought separately – 24 months. Claims and service are handled directly in Prague at our ASIC miner service.
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 1,980 Kč. If the price of any component changes, we recalculate the set price.
