Consider what design you need for a quiet computer.
Hello, you're thinking about creating a compact and mobile Windows PC suitable for working in various home environments. You'd like something lightweight, similar to an Intel NUC, but with silent operation and the ability to run two 5K monitors at 60Hz. It should resemble or be smaller than a Mac Mini and focus on office tasks rather than gaming. You're also considering whether a GPU might be unnecessary if the motherboard's integrated graphics suffice. What form factor would you need for the motherboard?
The maximum size specifications are H, W, and D. There are no weight limits mentioned. Portability is considered as the device being transportable.
These mini computers feature integrated 780M processors, similar to those found in the Steam Deck.
I don't need a strict size limit. As noted, even something as compact as an Intel NUC would be great. A Mac Mini works too, provided it runs quietly and has at least two 5K@60Hz displays plus a couple of 4K@60Hz ones. No gaming required.
For your needs, building a Mini-ITX PC might be preferable instead of purchasing the small Mini PCs you referenced. These Mini ITX models generally offer superior thermal performance.
Usually mobile chips perform better than desktop ones. Of course, you can adjust your power settings. However, even the tiniest Mini-ITX or DTX boards remain relatively big. The benefits lie in extra expandability and upgrade options. Maybe a 8600G or 8500G setup. Smaller chassis tend to be costly or hard to find. The most compact models often use Flex-ATX parts, which can be quite noisy. You might manage with a more expensive high-wattage unit if you pay the price. Chassis with SFX features usually provide enough space for a basic GPU, leaving unused room for other components.
Any computer equipped with a fan cannot be completely silent. However, it might be nearly inaudible. The power needed for the CPU is modest, and standard fans from previous models will likely not produce noticeable sound. Your issue seems more related to connecting the 5k monitors. What kind of monitors are you using and what connections do they need? If you plan to add more monitors, it might not be very convenient to move around. The built-in graphics on most motherboards are usually limited to one HDMI port and a few DP ports or HDMI connections. For a 5k display at 60Hz, a DP connection might be necessary. For compact setups, start with an ITX motherboard. It can support one dedicated graphics card, though any such card will probably include a fan and generate some noise. I don’t see a card that would run without a fan. You may need to modify your expectations to achieve quiet performance instead of complete silence.
What is your budget?
The issue with going down to Mini-ITX is that the parts usually target enthusiasts and gamers. You could easily hit the cost of, if not more than, a Mac Mini or another mini PC. Trying this out, I'm already looking at around $750 for the minimum, using a sub 15L case and something that's fully compatible.
