DIY NAS Freenas Server - Build your own NAS with Freenas

I had the choice between buying a prebuild NAS from the many manufacturers out there or simply building my own DIY NAS Freenas Server. I decided on the latter and will show you why this is a good decision.

Why build a DIY NAS Freenas Server?

Because it's more fun and you can adjust the hardware to your own special needs!  Being an avid photographer, shooting in RAW file format costs a lot of disk space, so it was finally time to extend my dated 2TB single hard drive storage. (I did backups of course)

Also, I wanted to build a proper Plex Media Server for a long time already.

DIY NAS Components

The budget was an issue, so I tried to find components that gave me the best bang for my buck.

I decided on the following build:

Of course, for hard drives, you can go according to your flavor, but I do recommend WD Reds or Seagate NAS drives. But keep in mind that Freenas wants 1GB of RAM for each TB of storage!

WD Red options

Seagate NAS HDD options

This whole setup should end up somewhere near a 1000$, I paid EU prices so the US might be cheaper.

It is powerful enough to stream in full HD to several people at the same time without a problem. (That is if your network is fast enough to handle the load.)

I decided to run with 4 hard drives in Raid-Z1 with single parity which gives me a total of 9 TB of storage. The case can handle a total of 6 hard drives, so you can go crazy if you want.

I used a 128GB Samsung SSD I still had lay around for my FreeNAS installation, total overkill, you can simply use a high-speed USB 3.0 Stick with SLC-NAND technology, which is built like an SSD, the mainboard has an internal USB 3.0 slot.

Building the NAS

Let's start with the build, all components together.

I had an immediate liking for the Node with its slick white minimalist design.

The inside of the empty case still looked spacious. Equipped with a huge 120mm cooler in the front and in the back a steady airflow to cool down the HDD's is guaranteed.

I began with assembling the mainboard. Still, lots of space I thought!

Time to assemble the CPU with the boxed cooler.

Now the fun begins! Time to screw the HDD's on the designated spaces. If you don't use the full 6 slots, make sure you leave some space between your drives to provide better airflow and overall cooling.

Neat!

Finishing the Build

Now let's put it all together. Side and top view.

Hard to do a proper cabling job on that, I put my maximum effort into it, but there is simply not enough space 🙂

Still not too bad! After putting it all together and switching it on I proceeded to install Freenas.

DIY NAS Conclusion

This DIY NAS Freenas Server has been running continuously since 2016 without failing even once. I didn't have to do any kind of maintenance apart from the occasional FreeNAS update.

I have been heavily using this NAS in the past 6 years for photography, lots and lots of video editing, and running a Plex Media Server on it. I usually only shut it down when I went on longer vacations, apart from that it was always running.

I couldn't be happier with the investment I made in the time and money of building my own DIY NAS Server. I can highly recommend it to anyone interested!

  1. I built mine on an HP Proliant DL-380eG8 server with 14 LFF bays. I have a dozen drives in the front that are the active ones. Six for Nextcloud, and six for Plex. They are hot swap drives and are used. I get them cheap ($50 for 3T) and using the built in RAIDZ2 of TrueNAS Core it provides adequate warning of a drive fail. I figure two or more failing at once is not happening. I can put a new drive in and resilver in a few hours. Cooling is great and power consumption isn't a big issue. The system has 64G of ECC Ram and e5-2450L CPU's with 32 threads... I really think this was an effective way to build. Total cost was $800USD. An occasional drive fail is a $50 replacement... and a few minutes of my time.
