Our data: where the information on HeavenPC comes from

The U.S. Consumer Product Safety Commission publishes the official recall notices for consumer products on CPSC product recalls. Each notice describes the products concerned, their model numbers and the remedy offered. We use this register first because it is an official source.

From it we take one field: the recall notice and its official link, shown on the recalled model. We checked all 270 models in the catalog. At this time, 0 recalled models were found, so no model currently shows a recall notice, and the register supplies data for 0 models out of 270.

To match a model to a recall, we first look for a candidate: a recall that names the model's brand and one of the listing's model codes. An AI model then reads the text of the recall itself and keeps it only if it concerns the same product and the same model, not a neighboring one, a battery or an accessory.

• Refresh: the recall list is checked again every month.
• Limit: a recall that does not give the model number cannot be matched with certainty, so it is not shown.

Each manufacturer publishes product pages, datasheets, user manuals and declarations of conformity on its own website, or on its group's website. Examples of such sites are Axcessables, VEVOR and Echogear. This is our second source in order of trust, after the official register.

This source covers 23 models out of the 270 in the catalog. We take these fields from it:

• Front door style
• Lockable doors and panels
• Rack depth, height and width
• Rail standard
• Ships flat or assembled
• Warranty length
• Weight capacity (rolling) and weight capacity (stationary)
• Wheels included

For each model, we search for its exact model number on the maker's own website. A figure is kept only when our server opens the page again and finds both the model number and that figure on it. Retailers, marketplaces, comparison or review sites and manual-collection sites are never used as a source.

Every model is researched once, and new models are researched as they join the catalog. Many brands sold mainly on Amazon publish no specification page; their models keep only what their Amazon listing states.

A model enters the comparison when it reaches a rating of 3.5/5 on Amazon with at least 5 customer reviews. Stock is not a criterion. The catalog currently lists 270 server racks.

Prices come from the product pages on Amazon.com and are updated every 7 days. The date each price was collected is shown next to it, and a model without a price is out of stock.

A model carries at most one badge, computed within its category. Most popular goes to the model with the most customer reviews. Top rated goes to the best rating among the models with at least 100 customer reviews. The rule shows on hover.

In the AI search, you describe what you need in one sentence. An AI model turns it into the comparison's filters, which you see and can remove. It writes no answer and only handles searches about server racks.

The quiz has 5 questions. The models that match at least half of your answers are kept and ranked from best to least match.

• Compare: up to 4 models side by side, with the best figure in each row highlighted. You can share the comparison with a link.
• Filters: each one has a "?" that explains it. The filters and the sort are written into the page address, which can be shared.
• Favorites: a heart on every product card. The list stays in your browser, and we never receive it.

Links to Amazon are affiliate links: we earn a commission on a purchase, at no extra cost to you. No manufacturer pays to be listed or ranked higher.
