The reliable desktop PC for office work and much more

The PrimeMini 4 is equipped with powerful Intel i3, i5 or i7 processors. Intel vPro technology simplifies the remote repair of PCs, which helps to solve hardware and software problems faster. In combination with Windows 10, the PrimeMini 4 provides a modern platform for productive work.

Thanks to the fanless design, the PrimeMini 4 desktop PCs are completely silent as well as dirt and dust resistant. This allows the use in environments where conventional PCs reach their limits. For example, in dirty industrial production halls or directly in medical treatment rooms.

The PrimeMini 4 can be configured individually and so everyone will find the right device for their use cases. For example, for an office PC, a low-cost Intel i3 processor with 8 GB of RAM is sufficient. If you work professionally with Adobe CC programs, you can configure a PrimeMini 4 with a powerful Intel i7 processor, at least 16 GB of RAM and a larger SSD hard disk. So enough power for the image or video processing and sufficient storage space for the work created are available.

Technical specifications

All benefits

Continued cost savings

Low power consumption, longer service life and zero hardware maintenance costs – using Prime Computer products saves you more than $ 2,000 per unit over five years.

Reliable and failsafe

The fanless design with no moving parts and high-grade branded components provides ultimate dependability. Costly downtimes resulting in business disruption are a thing of the past.

Fanless and maintenance-free

PrimeMinis stand for safety and reliability. Their innovative design protects them from wear and dirt and they require no maintenance. This saves time and money.


PrimeMinis start up within a matter of seconds. Regardless of the model, files and applications load quickly. Consistent high performance is achieved by passive cooling and ensures a vast improvement in day to day work efficiency.


Due to their passive cooling technology and closed housings, the PrimeMinis do not stir up air currents. Dust, microbes, pollen and other undesirable particulates are not sucked in and released back into the environment.

Dirt and dust-resistant

Dirt and dust particles can cause health problems, as well as damaging computers and servers. To combat this issue, the housings of the PrimeMinis are almost completely enclosed so they cannot draw in or circulate airborne particles.

Light in weight

Every PrimeMini is a lightweight, thanks to its aluminium housing and compact dimensions. Weight is less than one kilogram. There are no fans inside, and hence no voids for internal air circulation.


PrimeMinis operate entirely silently. They do not vibrate or produce electrical noise of any kind. The products do not contain fans or moving parts. A quieter workplace is a healthier one, and also allows employees concentrate better and work more efficiently.


Low power consumption, recyclable components and a long-lasting design: thanks to these advantages, PrimeMinis have a considerably smaller environmental footprint than conventional devices.

5 year warranty

We offer a 5 year warranty on every product. This is due to the high quality of the materials used, the sophisticated method of construction and excellent Swiss manufacturing. Each product is run through extensive testing before it is shipped to the customer.


A PrimeMini consumes between 5 and 30 watts – a very low figure for a product in this performance class. For comparison, a weak lamp uses around 30 watts. PrimeMinis can also be used on the road: a cigarette lighter socket provides sufficient power.


Prime Computer guarantees stable output throughout the entire lifecycle of the device. This saves time and effort for all IT managers. And it is also beneficial for private users who need to work reliably and efficiently.


PrimeMinis come in a handy size. Regardless of the model, their total volume amounts to less than one litre. For the average consumer, this means more office space. For IT administrators, it means more storage room.


PrimeMinis look as good as they work. The intentionally simple and clear-cut design gives them an appearance that is both timeless and elegant. Products can also be customised to meet special requests.


PrimeMinis are extremely reliable and have an above-average life cycle. This is made possible by the elimination of mechanical components and the use of high-quality components from established suppliers.


PrimeMinis deliver outstanding performance. They start up within a matter of seconds. Latest generation Intel processors and a powerful SSD hard drive ensure that the computers operate at full throttle at all times.


PrimeMinis are a Swiss development. The manufacturing processes and the quality control procedures take place here in Switzerland.

Reduced smog

PrimeMinis emit only low levels of harmful pollutants and electromagnetic radiation in comparison to conventional devices. These low readings promote improved well-being and health and reduce the environmental impact.


All our products are developed and manufactured in Switzerland. Prime Computer offers customer service and after-sales service and its service representatives understand Swiss German in addition to German and English. The service is fast, competent and always looks for the best solution.


PrimeMinis are suitable for very cold and very hot environments. This high level of flexibility protects the computers from sudden outages and loss of data due to fluctuating temperatures. The passive cooling technology enables stable operation at ambient temperatures from 0°C to 50°C. Operation above 50°C is possible with reduced output. PrimeMinis can be stored at even more extreme temperatures from -20°C to 80°C.


The housing as well as the packaging material consist largely of secondary raw materials, i.e. materials recovered by recycling waste. PrimeMinis are even 100% recyclable. Products can be returned to Prime Computer for recycling free of charge.


PrimeMinis weigh just over two pounds/less than one kilogram but have a very sturdy build. The devices can withstand mechanical stress and electromagnetic radiation without damage. Moreover, the products are insensitive to shock and vibration.

Money back guarantee

All Prime Computer products come with a 30-day money-back guarantee. If you are not satisfied with the purchased product, you can send it back to us. The repayment of the purchase price will be made within 14 days after Prime Computer receives the product.
