Proposal: Hardware Recommendations
The proposal should clarify that it's about computing hardware, not home improvement.
Anyway, since computing hardware goes obsolete on a regular basis, I don't see how the proposal could work. Software recommendations last longer because software titles remain essentially the same product from year to year. Hardware often needs to be completely reevaluated with each iteration.
The topic is covered by many forums. Maybe something like a StackExchange could provide timely, but dated advice. But SE answers are designed not to expire, and such a site would seem doomed to congestion with stale answers, perhaps not until well into the beta.
