How To Build Your Own NAS

The need to store files and access them from any device, from anywhere is becoming more prevalent in the realm of small office and home, and that is why more and more users are thinking about the acquisition of NAS.

Today’s technology network data storage, known as NAS (Network Attached Storage) is no longer exclusive to large companies, and we can find a variety of manufacturers recognized NAS devices specially designed for the home environment and to SMEs.

Unfortunately, one of the main factors why this technology has not been sufficiently popular is its price many times higher than a computer generation. This obstacle forces us to ask a simple question: Is it possible to build NAS yourself and save a lot of money?

Fortunately, the answer is yes, and in addition to saving money that we can manufacture our own NAS, we also have the ability to build it according to our own needs, present and future.

That is why in this article you will find all the information necessary to operate your own NAS, an adventure that could be considered also as an important step to your work flexibility.

Cabinet size: Which is correct?

Before making the decision to assemble a cabinet for NAS, the first thing you have to consider is what type of NAS you want to build. At this point, set the size to be the same is a major concern to keep in mind, since it depends on many factors such as the space available for placement, the number of storage units that will count the NAS and of course the budget available for investment.

In the case you are short on the budget, the truth is that the cabinet where you will stay the NAS can build virtually anything that can pierce. However, before reaching this point, you should try to get one though is used. A cabinet of these features can be very economical and can be found virtually anywhere.

Today, computers are replaced so often that it is even possible to find an old PC, including cabinet and hardware, with which to assemble the project, which we would only buy hard drives and a few other components.

As the size of the cabinet, provided that you have adequate space to locate it, no problem, it is more, bigger is better, because we can incorporate more disk without it being a problem.

What hardware do I need for my NAS?

Contrary to what you might think, you do not need to have powerful hardware to enjoy the benefits of a NAS at home or in the office. Moreover, the fact exaggerates NAS hardware may involve more energy consumed and greater problems at the time of dissipating the heat generated by these components.

There is no doubt that one of the most popular alternative operating systems for NAS is FreeNAS

This means you can use an old computer to arm your NAS, because with an old dual-core will suffice. In the event of having to buy new components, you must ensure that they are economical in energy use and heat dispersion. Nor do you need to be able to develop many Ghz speed, it is not necessary.

In the same plane is located on the motherboard, which can be as basic to find. The only point on which you should be concerned is that the motherboard provides as many SATA ports as possible, since this will depend largely on the capacity of NAS. It is also important to ensure that the motherboard provides functions such as booting from USB and wake-on-LAN. It is RAM that the computer will also not an item to worry much, because with 2 GB of RAM will be more sufficient.

Regarding the power supply, this not necessarily needed to develop many Watts of power, and to feed all that such a device need only be required standard power between 300 and 450 Watts.

The most important point: The storage capacity

The storage capacity is the most important factor in building a NAS, since you can keep at it depend on the amount of discs that we add to the set. At this point, it is best to purchase 7200 RPM hard drives, and that when they do transfer data faster. The amount of them in the NAS will obviously be based on your own needs, but a good idea is to start with a storage unit at least 1 TB capacity.

NAS construction

The armed internal arrangement of the components that make up the NAS does not differ at all with assembly of any desktop computer, except perhaps in the case that you have included in the project with several hard drives.

you must make sure to enable the function called Wake on Lan, Wake on Wireless LAN (WoWLAN) or WoL in the BIOS of the PC

After the assembly and commissioning of the NAS, you must make sure to enable the function called “Wake on Lan”, “Wake on Wireless LAN (WoWLAN)” or “WoL” in the BIOS of the PC, which will facilitate the task remotely turn on this machine in the event that is in a state of suspension. It is also a good idea to enable booting via USB.

Installing an operating system for NAS

There is no doubt that one of the most popular alternative operating systems for NAS is FreeNAS. This is because it is free, as it is an open source and free project, but also because it is very powerful and easy to configure and use, it is ideal for those users who do not have much knowledge on the subject.

However, you can also use any other operating system like Ubuntu, Windows or Openfiler, but the difference between them and FreeNAS is that the latter has been specifically designed for NAS, and therefore only includes the necessary options to be used for this purpose, without unnecessary tools like Paint or OpenOffice.


Assembling a NAS and subsequent commissioning is not a task reserved only for system administrators or technicians because with just a little knowledge and patience, you can have a device operating in a more flexible the way you access your documents. In addition, these systems are very low maintenance, and will not give you major problems until the end of its useful life.
