Building a budget bitcoin mining rig from an old PC in 2018 is very easy. I managed to build 4 GPU mining rig using old desktop computer and few easily accessible components.

The rig operates 2 GTX 1080 and 2 GTX 1060 MSI graphic cards, powered by stock PSU for motherboard and CPU, and 850W Corsair PSU to power the GPU's.

I decided to go this route, because I am not comfortable with my technical skills and I did not believe I could pull off building a new rig. Also, my funds were limited and this approach was a bit less expensive.

Under no circumstances I claim this route is better than building a new mining rig from scratch with new components. I also do not claim this is a cheaper route over all. Basic calculations would suggest it is, but it does not take under consideration at which point old desktop components will give up and will need to be replaced.

Also I am not sure about efficiency of old desktop computer PC based build. This video represents my own experience and opinion and it is not in any way a suggestion that this is a better solution for those on tight budget.

NEW BUILD RIG requires:

New Motherboard, circa $150, (solid brand)

CPU (processor), circa $50

RAM, circa $80-100, some $200

Motherboard power switch, circa $5

Windows License Key - Web, circa $35

TOTAL COST without GPU's $700 +


OLD DESKTOP BASED RIG ...easy build requires:

Old Desktop, circa $100, $200 for newer models with 8GB RAM HP 3400/3500 Pro
example [ Ссылка ]
This one is with 8GB RAM, which pretty much covers the difference between 4GB older unit and this one. eBay may be a cheaper option, but expanding and matching RAM for old units might be problematic. Hard Drives will also be old. Few things to have in mind. Return policy would be one of them as well. I have seen such old machines with Pentium CPU sell for under $100 on eBay.

PSU, circa $120

Please note newegg.com might have some cheaper options, $20 less or so.

GPU risers, circa $50

4 in 1 PCI-E Riser Adapter Board, circa $40

I used Mailiya brand.

TOTAL COST around $400, easy, almost plug and play set up.

My GPU's

I am mining with easy, plug and play NiceHash [ Ссылка ]

Initial earnings suggest it will take me about 12 months to get my investment back. 1 year old graphic cards should still hold some value and hopefully still be able to generate income.

I will attempt to cut my ROI period by investing in HashFlare [ Ссылка ]. Revenue forecasts suggest that sites such as HashFlare offer close to 50% return in 1 year period (contracts are 1 year long for HashFlare).

I plan to invest all of my initial income generated by mining int HashFlare and similar cloud mining enterprises.

I also plan to reinvest my cloud generated income back into HashFlare account to pile up my hash power.

By my rough estimate I should reach profitability in 6-8 months. Wish me luck :)

I am not suggesting anyone should follow my example. I am not a financial adviser :) so please don't treat my idea as a financial advice.

Here are most trusted and most popular Cloud Mining sites:

HashFlare [ Ссылка ]
Up and coming. Still affordable, but they have been steadily rising prices. I am already invested. Will increase my position.

Genesis Mining [ Ссылка ]
By popular opinion most reputable cloud mining company. Most of their contracts are sold out. That alone suggests how trustworthy this site appears to be. I am planning to invest here as well.

CryptoMiningFarm [ Ссылка ]
Very good referral program. Free Bonus with basic plan. In operation since 2014. No scam can last this long. Looks legit, IMO. Planning to invest as well.
