PC cases, cooling, and power specialist SilverStone has launched its new Alta D1 workstation chassis, and it is a big one. The marketing blurb heralds the new SilverStone Alta D1 as the “pinnacle of modular and flexible workstation chassis design.” Indeed, the scale of this chassis is impressively flexible, boasting of compatibility with specialist motherboards up to 15.12 x 13.2-inches, 11 PCI slots, GPUs up to 407mm in length, dual-PSUs, triple 360mm radiators, twin 5.25-inch optical drives, and much more. The new SilverStone Alta D1 has an MSRP of $799.

SilverStone has gone big with flexibility and capacity to try and make the Alta D1 a compelling offering. The product pages show examples of an Alta D1 build / layout purposed for hyper-converged, high-computational, and AI development systems. They are all packed with GPUs but vary with their cooling, storage, power, and motherboard choices, as appropriate. A big factor in the Alta D1’s flexibility is its modular bay construction, which accommodates a range of modular cages and fan/radiator brackets.

When you check through the specifications table you will perhaps start to appreciate the Alta D1’s sheer capacity and flexibility – plus options for customization. However, this is a large case, measuring 265 x 651 x 457mm (10.43 x 25.63 x 18-inches), and 78.84 liters, and weighing 21.3kg (~47 pounds) unpopulated.
Other features we feel compelled to bring to your attention are the 11 expansion slots with 1.5x height clearance, and the preinstalled 2x 180mm intake fans and 140mm exhaust fan. Moreover, there are the twin 5.25-inch bays – a rarity nowadays – for optical drives, disk caddies, etc.
SilverStone previously showed off the Alta D1 at Computex 2023 and 2024. So, it is good that it has now, at last, hit retail – even at the $799 MSRP. If you would like wheels for your D1, they are listed at an extra $20, which can’t really be complained about.
