Does the choice in processor, or harddisk, or board make some difference in the security of a computer-system? It doesn't have to be much difference but would e.g. an Intel-system be slightly more secure than an AMD-system? Considering that modern hardware tends to come with some possible bugs and/or possible exploits, I could imagine that some hardware components would be less vulnerable than other, similar hardware components. So I wonder, which hardware brands are best-known for the least possible vulnerabilities and bugs? (And not just processors, btw!)
