**the short version:** The same eight-part desktop, read again on 1 November 2026 between 06:21Z and 06:43Z, before tax and before shipping. Everything but the graphics card is $1,349.48, against $1,348.87 on 13 September: a change of $0.61. The card is where the money went. The cheapest new NVIDIA GeForce RTX 3090 (24 GB) of any brand was $2,399.00, a tracker's reading of an Amazon marketplace listing, up 31.1 per cent from the $1,829.99 the parent page read; the rig at that card is $3,748.48. A typical used card, the median of 161 completed eBay US sales between 8 and 15 October as InsiderLLM reports them, was $1,499.00; the rig at that card is $2,848.48. On one source's own figures the used card rose 17.6 per cent from August to October. The renewed listing the parent page priced still exists at the same $1,849.99. Twelve used or renewed listings were found between $1,500 and $2,040, eight of them on Amazon between $1,729.99 and $1,949.99; none of the Amazon eight was under $1,700. Four of the seven part prices are search snippets, and the page says so row by row.

This page re-reads the bill of [the rig at the top of this shelf's price series](/home-inference-and-diffusion-rig-cost/), a consumer desktop around one NVIDIA GeForce RTX 3090 with 24 GB of video memory, seven weeks after that page priced it, because the card's price has moved. The parts list is the parent page's; only the prices are new.

## What was read, when and how {#what-was-read-when-and-how}

Every figure here was read between 06:21Z and 06:43Z on 1 November 2026, at US retailers, in US dollars, before sales tax and shipping. The window is the receipt: prices moved before you read this. Every price carries a grade. **A**: read on the retailer's own product page. **B**: read on a price tracker listing that retailer. **C**: a search-result snippet, not read on the page, capture time unknown. **T**: a published aggregate, a median or an average, with the source's window and method, or a retailer's "from" line, the lowest of several sellers' offers.

The retailer the parent page priced from, amazon.com, served all but two of the product pages this workshop's fetcher asked for (those two returned a server error) and withheld each product's own price ("To see product details, add this item to your cart"). What it did show was the "Other sellers on Amazon" line, the tiles of its "consider these" carousels, and whether an item was in stock; those are recorded as what they are, never as a product page's own price. Most other retailers refused the fetcher outright, so where a page could not be read, a price tracker or a search snippet was, and each row's grade says which. Of the seven parts, three are grade B and four are grade C; none is A. The one in-stock A-grade part price found, the power supply at the maker's own store, is $289.99, $50.00 above the street price three snippets agree on.

## The bill, September beside November {#the-bill-september-beside-november}

The parent page's eight parts, by the same titles. A row is the best grade available, and among snippets the cheapest price two independent sources agree on; the cooler's snippet has no second source.
