Leha ho le joalo, the latest 2014 Mac Mini has soldered-in memory and is due for an update.

Quiet PCs

Building quiet PCs used to be an art that involved specialised components, such as fanless power supplies and liquid cooling, added damping for rotating drives, and paying attention to the airflow through the case. I assume Chillblast still does some of this. Leha ho le joalo, things are easier today, because companies can start with barebones cases like the Shuttle and small ITX motherboards, or just use a tiny Intel NUC (Next Unit of Computing).

The NUC usually includes a large heatsink and a small fan, so I would not expect an off-the-shelf version to be silent. Leha ho le joalo, some companies have designed NUC cases that, in essence, work as large heat sinks. Ho hlakile hore, you wouldn’t run one in a confined space, but in normal conditions, they can radiate enough heat to stay within the TDP limits.

Quiet PC’s UltraNUC is an example, with systems being built-to-order in the UK. The UltraNUC Atom version starts at £325, while the Abel-cased UltraNUC Pro fanless starts at £595. Quiet PC also offers many other silent or quiet PCs, media centres and entertainment systems, so you might find something that suits you better.

Aleutia’s R50 Fanless – “carved and crafted in the UK” – is a robust but classy-looking NUC variant. Leha ho le joalo, it’s really intended for industrial and commercial uses. An R50 standard with a Core i3, 4GB of memory and 60GB SSD costs £599. Aleutia also sells a T1 nettop “Eco PC” with a Celeron J1800 and 2GB of memory for £349, or with 4GB, a 120GB SSD and Microsoft Windows for £499. Tiny Green PC is an alternative supplier.

In all the above cases, double-check to see if the price includes a copy of Windows. Most do, but some mini PCs are sold without an operating system for people who want to run Linux.

Last words

Most modern desktops now run quietly, except when stressed, and the trend towards low-TDP Atom processors and SSDs is making them even quieter. (You can check the TDPs and benchmarks of different chips at Notebookcheck’s Comparison of Mobile Processors.)

The questions you now have to answer are (e) how much power do you need, le (b) how much are you prepared to pay for silence?

If you want to make recordings in the same room as your PC, bear in mind that a mouse-wheel may make a clicking noise – yes, I’ve been caught out by that – and keyboard use is probably out of the question. There are times when a touch-screen has the advantage of being quieter.
