This was brought up on Area 51, but I don't think it was sufficiently addressed.
Taking into consideration the following:
The primary goal of a Stack Exchange site is not to simply provide an answer only to the user who has asked the question—the "mission statement" of all Stack Exchange sites is to build a repository of high-quality Q&A for future visitors. From the Tour:
Hardware Recommendations Stack Exchange is a question and answer site for people seeking specific hardware recommendations. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about hardware recommendations.
The majority of traffic to Stack Exchange sites comes from search engines. Therefore, if the questions on a site generally don't continue to be useful for... ever (or at the very least a few years), then your site simply isn't going to work on Stack Exchange.
Hardware outdates incredibly quickly. The A51 post I linked mentions that Stack Overflow and other SE sites (most prominently, Software Recommendations, of course) have the same problem, but they simply don't have it on the same scale. Hardware outdates exponentially more quickly. A simple example, from mkomo.com:
And one from preshing.com:
Note the log scales on these graphs. This is a problem unique to Hardware Recommendations, even though other sites may have it on a much smaller scale—and if we don't find a really good solution, I have very significant doubt as to the success of this site.
An outdated question is a useless question. This probably goes without saying, but especially in the case of HR, a question such as "what's the best frobble that I can get for under $200 with feature X and specs Y and Z?" that gets answered and then ignored for a few years will become completely worthless. This is the polar opposite of the Stack Exchange mission.
So, what's the solution to this problem? How will the community handle this?
