SC Spectre 3.0 Antumbra PowerBoard Edition Black

USD $1,869.15


Limited Edition: Limited to 24 cases.

Spectre 3.0 Antumbra is the next limited edition dark version of Spectre 3.0 inspired by the different shadows created during an Eclipse. It has an updated version of the triple layer distribution plate with a black central layer, grey tinted rear layer, and clear front layer, making it darker than Penumbra. The reservoir and cable management areas are transparent and still visible from both sides. The reservoir has twice the fluid volume compared with the stock Spectre 3.0 reservoir, and the design has been updated compared to Penumbra to have more symmetry and a different style. The logos have been updated and there is a new logo on the back of the distribution plate which displays the unique product number.

Introducing the Singularity Computers PowerBoard.
Antumbra comes included with the Spectre 3.0 PowerBoard. The PowerBoard is a PCB integrating 24pin, PCIE and EPS along with PWM and ARGB Hubs and LEDs. The LEDs are positioned around the perimeter of the PowerBoard to optimally light up the distribution plate. Essentially the PowerBoard is a distribution plate for cables also integrating other features and functions. It is a new method for cables and cable management making cable management no longer necessary and the cables much cleaner.
Spectre 3.0 Antumbra is fully compatible with Spectre 3.0 and Spectre 3.0 Elite.

ETA: 3 weeks

Integrated Liquid Cooling Features:
Reservoir, D5 Pump Top, D5 Pump Cover, Fill Port, Drain Port, roughly half of the cooling loop.
Integrated Cable Management Features:
Cable management channels with cable combs. 3x 8pin EPS on the left side of motherboard and up to two above the 24pin. 24pin Cable. SATA Data x2.
6x PCIE go through the PSU Top Shroud.
Reduced build time due to integration:
With the pump and reservoir combo and roughly half of the loop integrated there is less assembly to be done. Also, less fittings and tube are needed.
Cable management is also quicker, just clip your cables into the integrated cable combs and they are all perfectly aligned.
Integration Cost Component:
A large portion of the case cost is due to the integration. These are components you do not have to purchase for your build. The pump and reservoir combo, less fittings, less tube, no cable combs, or cable management components.
Theoretically the more integration the less compatibility. For Spectres integration the position of each integrated port and cable routing hole was carefully chosen based on statistics and our experience.
Integration & Optimization:
With the integration we did not just develop a case, we also had to develop all the integrated components. This meant that we could focus more on optimization than would normally be possible. The integrated loop routes in Spectre allow for more flow than 16mm tubes.
The pump top was designed for the D5 pump, maximizing flow to and from the distribution plate.
The reservoir was designed to remove air as quickly as possible making the loop easier to fill.
The fill port is at the highest point on the back for the case and the drain point at the lowest point.
The cable channels and combs are designed for 4mm sleeved cables. They can be clipped in very quickly and there is far less work to do for clean cable management. 
High End Components:
Spectre 3.0 fits XL-ATX motherboards and has 8 expansion slots. It is designed for fit up to two RTX 3090s. It can fit the largest PSUs up to 220mm. For the cooling system it can fit 2x 360mm radiators 60mm thick with a single set of fans or 2x 360mm radiators 40mm thick with two sets of fans, and the powerful D5 pump.
Radiator Adjustment:
The radiator mounts have a large range of adjustment to help with port alignment to the distribution plate. 
Spectre 3.0 has 6x 2.5” Drive positions. Two are on the top of the PSU shroud and there are four inside of the PSU shroud. The two on top of the PSU shroud cannot be used with vertically mounted GPUs.

Manufacturing & Quality

Every component of Spectre is CNC machined from a solid block of material. With the level of transparency and being an open case, we wanted it to be a celebration of the raw materials. There is no hidden or back side, and this also goes for the components being installed. Due to this we selected the most high-end materials manufacturing process. The Distribution Plate is machined on a CNC router built from thick sheets of cast acrylic. It is hand assembled with silicone gaskets and stainless-steel fasteners, and pressure tested. The metal components are machined with Extreme Precision from solid blocks of 6061 aluminum on a CNC mill then sand blasted and anodized.

Design & Engineering

We are all experienced system builders at Singularity Computers having built high end water-cooled systems for over 15 years. Our approach to product development begins with a need for our own builds and so the origin is always function. From there we start to build ideas around this function and the aesthetics and everything else follows. The original idea for Spectre came from our years of building highly customized, high end water-cooled systems and trying to reduce the exceptionally long build times and complexity. Our approach to development is very hands on, we are doing real world testing every day.
The aesthetics of Spectre originate from its function with one of the main aesthetic features (the lighting) being something only made possible by the integration. We wanted the case to look skeletal and almost transparent enough to (in a way) disappear around the components. The metal components have been designed to enhance this with an extreme focus on detailed and complex multi sided CNC machining.

    We have standardised cable lengths for the PowerBoard. Here are the details, contact  with any further questions. These cable options will be available at cable builders and on our site soon:
    PowerBoard Linking Cables: Motherboard and GPU Side: 1:1 Cables with female connectors on both sides. (there are two lengths on some cables because the inner wires need to be shorter for the tight bend).
    24pin: 18.7/20cm.
    8pin EPS: 18.7/20cm.
    4pin EPS: 18.7cm/20cm.
    8pin PCIE: 30cm.
    8-pin to 6pin PCIE: 30cm.PSU Side Cables: PSU specific pinouts with female connectors on both sides. The amount of cables is standard for every PowerBoard.
    1x 24pin PowerBoard PSU Cable Set: 20cm & 30cm option.
    2 x 8pin EPS: 20cm & 30cm option.
    3 x 8pin PCIE: 20cm & 30cm option.
