With the Lenovo D20 looking like it could be too loud, I reduced the list of possibilities to the hp Z800 and the Dell T7500. The hp workstation wins the design competition: nearly everything snaps together and requires no tools to access – it’s actually a step ahead of the Mac Pro, and the Mac… [Read More]

Fortunately, there is an internationally standardized test procedure for computers and workstations, ISO 9296. Unfortunately, it’s difficult for prospective computer buyers to get the numbers….
