ION has been building custom computers, primarily servers, for more than 27 years. ION's products can be branded or unbranded or branded for you. ION provides very thorough documentation including pat numbers and serial numbers for all major components, both on paper and on-line, including detailed photographs of the system. And every ION server includes "scorpion", a bootable USB tool with programs to diagnose and capture data about the system for ION to assist in troubleshooting, whether or not your target operating system has these capabilities.
