In an earlier post, I shared a design for a Chia plotter/farmer based around the Intel NUC NUC10i7FNH tiny computer.
Today I built that machine, and it’s running its first plot as I type this.

Here’s a quick rundown of what was involved in the process.
Feel free to shop in your preferred venues online or locally, or if you already have components, use them. These links are Amazon affiliate links, and if you use them, I get a few bucks to go toward my next hardware adventure. (I bought my NUC and RAM from Central Computer, a local computer store in Silicon Valley, and the NVMe drive came from Amazon.)
Base computer – NUC10i7FNH1 currently $570 at Amazon. You want the i7, and you want the FNH which is the “high” case that holds a 2.5″ drive as well as the m.2.
RAM – 32GB (2x16GB) DDR4 2666 or better SODIMM. Crucial 16GBx2 kit around $182 at Amazon. You can install 64GB, but you probably don’t need it with this processor.
Boot drive – I used a Samsung PM851 that’s not available on Amazon at the moment. Any 2.5″ SATA drive will do, even a HDD. Amazon has the WD Blue SSD 250GB for $45 or 500GB for $60. If you have something else on hand that’s at least 120GB, go ahead and use it, or if you want some internal plot storage, get something bigger.
Plotting drive – 2TB Inland Premium NVMe is popular with its 3200TBW rating, about $240 on Amazon but out of stock for the next week. If you watch your drive life, you can use cheaper NVMe or even SATA m.2 storage. But check the TBW (Total Bytes Written, or Terabytes Written) and warranty for your drive and take that into account.
OS install drive – Get a USB 3.0 drive with 16GB or more space, and use Balena Etcher or Rufus to burn Ubuntu 20.04 LTS to it.I like the Sandisk Ultra 32GB for price point and quality, about $10 at Amazon.
External long-term plot/farm storage – I’ll be using an 8TB external drive in the near term, but you can use whatever you have, even NAS storage.
Bonus: Staging disk. A user on r/chia suggested using a staging drive to copy your final plot file to, so that your plot process ends faster than if it has to be copied to slow disk. You can then automate moving the plot files to your external HDD at your leisure, and get back to plotting again up to an hour faster. For this, you can use an external USB 3.0 or better SSD like the WD My Passport SSD ($150 for 1TB), Crucial X8 ($148 for 1TB), or pretty much any SSD that will hold a batch of your plots (1TB will hold 9 plot files). You can also use a directory on your NVMe drive for this, but make sure you don’t let it fill up.
