ATX version
ATX (Advanced Technology eXtended) is a motherboard form factor specification developed by Intel in 1995. The specification defines the key mechanical dimensions, mounting point, I/O panel, power and connector interfaces between a computer case, a motherboard and a power supply. There are many versions of ATX including ATX12V 1.x and ATX12V v2.3.
Parallel processing technology support
Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs.

This indicates that the product is compliant with Energy Star, which is an international standard for energy-efficient consumer products.
RoHS compliance
The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.
