Over the past 18 months or so, I've been working on a project and it's aim was to create a quiet, extremely powerful and compact computer. Something that can live on a desk as well as a home theatre cabinet.
Typically, when talking about PC's, those three adjectives can't really be used together, as powerful PC's usually draw a lot of power and exert a lot of heat, therefore need a lot of cooling, which is usually loud. This is how project Orthrus was born.
The name, which is only a working title for now, stems from Greek mythology. Its a symbol for a two headed guard dog (symbolizing the use of dual GPU's). Coincidentally enough, Orthrus was Cerberus' brother (My shout out to Kimera Industries guys here)
Principal of the design:
As mentioned previously, high performance computer parts and compact enclosures usually don't go well together. That is unless you move the components in the case around in a way which allows all of them to draw fresh cold air from the outside of the case.
Putting the dual GPU's straight on the back of the motherboard, not only allows the two GPU's and the CPU to breathe their own air, but allows to minimize the width of the chassis, by putting the only 2 perfectly flat parts of the PCB's against each other.
To achieve this, a number of design decisions were made:
- PCIe risers had to be used to place the graphics cards on the opposite side of the case.
- Longer than usual SLI cables had to be used to join the graphics cards together
- Only 2,5" disks would be used (when using both GPU slots), as 3,5" disks are too big, and with the cost of 1TB SATA SSD's quite low these days, I didn't see a point.
