Oh now this is spiffy!
The aluminium-cased Cirrus7 Nimbus is tiny, measuring just 22cm x 22cm with a height a smidge over 5cm.

But since “mini-PCs” aren’t exactly hard to find Cirrus7 have made sure the Nimbus will stand out by making it fanless. From what we can discern the aluminium case is also a passive cooler, able to tame the heat from an Intel Core i7-3770T with a max TDP of 45W.
