Colominer – Legit GPU Cryptocurrency Mining Rigs Pre-Orders?

Colominer is an online store where you can buy various cryptocurrency miners. Read our review to find out if they’re legit today.

What Is Colominer? is an online store featuring GPU server cases and mining rigs. The company assembles miners, then sells them online to customers. They also offer installation services: you can ship your hardware to the company, and they’ll build and test your rig for you.

Colominer appears to be a legitimate mining rig reseller. The company is open and honest about the parts being used in its rigs, and they’re very active on social media. They also seem to offer a generous 180 day limited warranty. However, the company has no refund policy.

Colominer is based in Edmonds, Washington. The company’s rigs are designed to mine Ethereum, Zcash, Monero, and other GPU-mineable coins.

Colominer has been promoting its pre-sales in recent weeks. The company is building several hundred units of two different miners. You pay a $500 refundable deposit today, then deliveries start in October.

Colominer Rigs And Pricing

Colominer currently offers two different rigs, including each of the following:

  • Colominer 4U Bulbur 8 GPUs Miner: $4250 (using RX 570 4GB cards)
  • Colominer 6U Phoenix 12 GPUs Miner: $6500 (using RX 570 4GB cards)

The price for both rigs is listed as $500 at the top of the page. However, this is listed as a refundable deposit. The remaining balance for the rigs is due before your order is shipped. The prices we’ve listed above may change, depending on ongoing negotiations with Colominer’s vendors.

Neither unit comes with a displayed hash power, because both models are customizable to use any combination of RX 500 Series GPUs.

For example, if only RX 570 4GB GPUs are used inside the 4U Bulbur unit, then the total hash power will be around 192 mh/s. On a 6U Phoenix unit, the total hash power will be around 288 mh/s.

Colominer also doesn’t use overclocked GPUs because it would void the factory warranty.

Colominer Refund Policy

Colominer has a 30 day refund policy, although it only applies to items that are unused and in perfect condition with their original packaging. If you’ve already used your miner, then you won’t be able to get a refund.

Colominer will, however replace items that are defective or damaged. The company has a 180 day limited warranty. When your rig is under warranty, Colominer will repair the miner at no charge using new or refurbished replacement parts. You pay all shipping charges.

90 days of technical support is also included with all miners.
