Limited Customisation Options

We’re pleased to announce that all backers of the Circumference 25 Early Bird and Early Access pledge levels will now get to pick from one of eight colours for the acrylic enclosure, and another eight colours for the compute node access door.

A C25 in Pale Green (6205) and Green Transparent (6600) Perspex.

For details of the available colours options, including their Perspex colour references, see the main campaign page. If you’ve already made a pledge and would like to change your options from the default, please submit your choices to us through the campaign question form.

In addition, backers of these pledge levels also have the option of having a custom logo or text — e.g. company, project or just your name — engraved on the wood veneer front panel.

The custom logo option is also being made available to backers of the Circumference 100. Logos will be collected before manufacturing begins.

At this point in time we don’t plan to offer custom colour or logo options after the campaign closes.
