Most gaming PCs deal with heat by getting it out of the case as quickly as possible. The AFTERSHOCK cherry blossom PC gives some of that warmth a second job: opening the flowers on a handmade tree inside the system. Seventy hand-painted blossoms turn the activity of the hardware into a changing display, with the tree responding to the thermal conditions around it.
We saw the CHERRY BLOOM build at PAX and wanted to know how the idea worked beyond the glass. How do the petals move, how does air reach the graphics card, and how do you balance cooling a gaming PC with keeping its flowers warm? For this feature, Justin Nguyen, Head of Marketing at AFTERSHOCK PC Australia and the build’s designer, answered our questions in writing about the mechanism, development and finished machine.
The Melbourne builder developed the PC in collaboration with ZOTAC, combining custom CPU watercooling with an internal sculpture that reacts to gaming heat. The result brings together case design, materials science and some very patient craftsmanship. It also gave the team an unusual problem: during development, the cooling was doing its job a little too well.
From a cherry blossom theme to a moving PC
Cherry blossoms were already familiar territory for AFTERSHOCK. Nguyen says the theme had been popular with its customers for three years when he saw a blossom mechanism from HTXStudio. That provided the starting point for a version that could live inside a gaming PC. The appeal was the relationship between the movement and what the machine was doing.
“What really excited me was the connection to gaming itself,” Nguyen tells TechDrivePlay. As a game asks more of the hardware, the system generates heat, giving the artwork a physical way to respond. In his description, the tree should bloom alongside the activity of the PC, making the visual effect part of the experience of playing.
That relationship gives the design a different rhythm from a programmed lighting sequence. A demanding game changes conditions inside the case, and the material in the blossom mechanism responds. The effect depends on the physical environment that the builders have created around the tree, which makes the placement of every branch and the movement of air important.
Adapting the idea meant fitting the mechanism, hardware and sculpture into the same enclosure. The tree needed room for its moving parts, while the components still needed airflow and the finished design had to feel coherent. Those constraints shaped the engineering from the beginning.
How the heat-reactive cherry blossoms open
According to Nguyen, the mechanism uses Nitinol, a nickel-titanium shape-memory alloy. Its internal crystal structure changes with temperature, allowing it to recover a preset shape as it warms. In the CHERRY BLOOM mechanism, that change produces the opening movement of the petals. As the material cools and becomes more flexible, the mechanism allows the blossoms to return towards their closed position.
Nguyen describes the warmer phase as austenite and the more flexible phase as martensite. Those names explain the material behaviour, but the useful point is straightforward: temperature can create mechanical movement. The blossom mechanism can therefore respond passively to its surroundings, without a motor or an electronic command telling each flower to open.
The quoted opening and closing temperatures need a little context. Nguyen says approximately 27°C for opening and 18°C for closing refer to the thermal response of the Nitinol mechanism itself. They are not CPU or GPU temperature readings, and they should not be read as cooling targets for the components.
The difference between the opening and closing temperatures is thermal hysteresis. Put simply, the material takes a different temperature path as it warms and cools. The flowers therefore respond to the conditions at the mechanism, rather than acting as an instant visual readout of a number in monitoring software.
That also means switching the PC off is not a mechanical close command. Cooling the surrounding area sufficiently is what allows the return movement described by Nguyen. Room temperature, airflow and the warmth remaining in the case all help explain why the display is tied to its environment.
Designing the tree around the graphics card and cooling
AFTERSHOCK started with the working PC, then built the tree around it. Nguyen says the team assembled the hardware and custom CPU watercooling first, took detailed internal measurements and developed the 3D model from there. That gave the designers the real dimensions and obstructions they needed to work with.
The tree went through repeated modelling, test printing and work on its mounting points. Its internal structure was hollowed out so the bottom intake fans could continue feeding cool air directly towards the GPU. A substantial trunk may look solid through the side panel, but its shape was developed with an air path through the structure.
The flowers sit higher in the case, where rising warm air could help activate them. In principle, that arrangement gave the team a way to supply the graphics card with cooler intake air while placing the canopy where it could respond to the system’s heat. Getting both effects to happen consistently took further adjustment.
Early testing revealed that heat was leaving the case so efficiently that the whole tree did not reliably bloom. Nguyen says the team made small fan-curve adjustments to balance blossom movement with hardware cooling. He describes maintaining good component temperatures as the priority throughout that work.
“It’s not often that cooling a PC too well becomes a creative challenge!” he says. It is a useful detail because it captures the central design task: the builders were managing how warmth moved through the case as well as how quickly it escaped.
Two months of modelling, building and adjustment
The original announcement described a two-month process of making, painting and assembling the custom elements. Nguyen’s account adds the less photogenic work behind the finished tree: test prints, mounting solutions, airflow adjustments and repeated changes as the team learned what worked inside the case.
He describes development as a collaborative process, with ideas changing through building and testing rather than following a fixed blueprint from start to finish. The main challenge was balancing the visual ambition with the requirements of a working gaming system. The tree’s form and the cooling behaviour had to develop together.
The supplied close-up images show why the finishing work matters to the overall effect. Pink and white petals, painted centres and dark branches give the canopy its character, while the trunk carries that design down through the hardware. With 70 individual flowers, the repeated details become a large part of the piece.
That is also why the development story extends beyond choosing a component list. The team had to adapt a heat-responsive idea to a particular enclosure, make it fit around a liquid-cooled system, and finish the result as one complete design. Each of those decisions affected what could happen elsewhere in the case.
What happens when the PC starts gaming?
Nguyen says the finished system went through AFTERSHOCK’s usual quality-control procedures, including stress testing, thermal monitoring and checks of the custom CPU watercooling. The team then used real gaming workloads to examine how the system and the tree behaved together. The build was developed as something customers could own and use at home.
Alongside hardware temperatures, the builders watched how consistently the flowers moved under different loads. Nguyen says airflow and fan behaviour made a meaningful difference to the response, which fed into the final adjustments. This gives a practical reason for the testing to cover both the electronics and the artwork.
His example is suitably specific: something like Hello Kitty Island Adventure might leave the tree short of a full bloom, while a demanding title such as Cyberpunk could bring it more fully to life. That is the designer’s illustration of workload-dependent behaviour. It should not be interpreted as a fixed bloom time or a guaranteed result for every room and game setting.
The interesting part is that the display follows a consequence of the workload. A heavier game can produce more heat for the surrounding mechanism to respond to. The tree gives that normally invisible part of a gaming session a visible presence inside the case.

Living with 70 handmade blossoms
A moving sculpture inside a PC naturally raises questions about cleaning. Nguyen says the 3D-printed tree and metal blossoms were designed for everyday use. His maintenance advice centres on the familiar problem of dust, with extra care around the petals, finer details and custom watercooling components.
He recommends gentle compressed air and light cleaning with a soft brush, even something as simple as a makeup brush. Direct pressure on the petals should be avoided. The aim is to remove dust without forcing the mechanism or disturbing the detailed parts of the build.
For anyone planning future internal changes, the tree and custom loop are worth discussing with the builder before work begins. Nguyen’s answers do not set out a specific upgrade or disassembly procedure. Getting advice for the exact job would preserve the relationship between the hardware layout, cooling and handmade components.
Australian price and whether you can order one
Nguyen confirms that CHERRY BLOOM was developed for customer orders, with the same blooming experience shown at PAX. The approximately A$20,000 figure in the interview covers the configured PC, its hardware, custom watercooling and handmade tree with heat-reactive flowers. He says the flowers account for a substantial portion of the work and cost.
At the time of writing, the Australian CHERRY BLOOM listing shows A$19,995. It also lists a three-year hardware warranty and lifetime technical support. Buyers should check the current configuration, price and delivery arrangements directly with AFTERSHOCK when ordering.
The part of CHERRY BLOOM that stayed with us after PAX was the connection between the game and the sculpture. Nguyen’s answers explain the work behind that connection, from shaping the hollow trunk to adjusting the fans so the canopy receives enough warmth. A familiar by-product of gaming becomes part of what the owner gets to watch: the hardware gets busy, and the flowers begin to open.
