Felix at Billet Labs set out to park a real gaming PC in a living room and leave the fans off. A Ryzen 9 9800X3D and an RTX 5080 share a Gigabyte AORUS Pro B850 board, fed by a 600 watt Flex ATX supply, and the pair can pull well past 500 watts once a demanding game settles in. Air coolers handle that load by moving a lot of air. Moving a lot of air makes noise. An earlier attempt had hung the same idea on a cast iron radiator and ended near 100 kilograms, so this version started over on a hand-worked aluminum block that brings the finished machine down to about 15.7 kilograms once the loop holds roughly two liters of water.

Researchers at the Singapore University of Technology and Design built a small robot that leaves a drone, spins on the way down, and keeps moving once it meets the water. They named it ALBATROSS, short for Airborne Lander with Buoyant AuToROtating Sailing Sensor. Lead author Shane Kyi Hla Win, working with professor Foong Shaohui, describes the machine in Science Robotics as a way to put sensors on a lake or a sheltered stretch of sea without sending a boat out to meet them.

Broad Arrow will offer the only Daytona Shooting Brake Hommage this Friday at the Zoute Concours Auction in Belgium, lot 172, with an estimate of $450,000 to $650,000. Dutch studio Niels van Roij Design spent about 15,000 hours on the car, a one-off coachbuilt body on a 2009 Ferrari 599 GTB Fiorano, chassis ZFFFD60B000160781, with 43,802 km recorded at cataloguing. Its public debut came July 8 on the lawn at the Royal Automobile Club, Woodcote Park, while the mechanical parts stayed as Ferrari delivered them.

Apple put a new Mac Mini M6 on the market in late September, and by the first week of October the base model was already cheaper. Amazon has the entry version at $779.99, down from the $899 list price, as part of the October Prime Day run. That is the first cut on a machine that only just reached stores, and it lands on the configuration most people will actually see: 16GB of memory, 256GB of storage, and the standard M6 chip.

Astronomers filed a strange spectrum of the white dwarf HS 0209+0832 in 1999 and left it there. Hubble had recorded roughly 100 chemical features that no catalog of the time could name. The star itself is the bare core of a low-mass sun that burned through its fuel, shed its outer layers, and settled into a compact remnant. At about 35,800 degrees, with a cooling age near five million years, it is still young as white dwarfs go, and still hot enough to strip gas from anything orbiting close in.
