Sort of, but some hardware supports security features that other hardware does not support. For example, K series intel processors allow for overclocking, but non-k processors have support for IOMMU which is required for strong isolation. Newer processors support a range of security features not available on older processors. Different motherboards have different security features as well. Then there are things like Tresor, which requires AES-NI I believe. Software plays a big role, but it needs hardware support and not all hardware supports all security software. Thankfully laptop hardware tends to support pretty much everything, for desktops it is a bit more specialized. My advice is to get a laptop from a custom builder, not a major retailer like Newegg. Then you can automatically save a hundred dollars by not getting it bundled with Windows or other bloatware. You can also customize the hardware etc. Yuck Alienware is like the Mac of the Windows laptops. Overpriced as hell and largely a marketing company. You can get an equal laptop for much less, Alienware is all about the brand name. The only real advantage of Alienware laptops is they seem to support overclocking the CPU a bit more than other laptops,but honestly you are not going to overclock your laptop CPU much anyway. Alienware laptops also weigh a metric fuckton compared to similar offerings from other companies. Mac laptops are like Alienware, way overpriced for what you get. At least they have really nice screens. I can recommend Lenovo. They have the highest overall build quality of all laptops that I have seen. They do tend to be more business oriented though, usually they do not have gaming GPU's but rather workstation GPU's. One good thing about Lenovo laptops is that they support manual GPU switching from BIOS instead of the Optimus nonsense, so you can easily use the dedicated GPU with Linux.
