Steam Machine price starts at a high level, data-mining on Czech retailer listings shows

Two Czech e-tailers have surfaced as the latest “price leak” candidates for Valve’s upcoming Steam Machine. The numbers are coming from page code and tracking payloads, not from any public checkout flow, and that context matters.
The original claim came from a Smarty.cz product page where the visible listing does not show a customer-facing price. People digging through the page source reported hidden values for two configurations. A 512GB model was shown at 19,826 CZK (~950 USD), while a 2TB model appeared at 22,305 CZK (~1070 USD). Prices do not include VAT.

After that post spread, another user checked Alza and reported a similar setup. In the Alza page data, the Steam Machine shows up as a catalog item name (“Valve Steam Machine”) with a price field attached, even though the store page is not presenting a finalized retail offer yet. This is what you can find inside the page code:

Speaking from experience, this is a common pattern for unreleased hardware pages. Retailers create placeholder listings early for search traffic and indexing. The backend still needs a numeric value for analytics, internal catalog tooling, or templated “from” pricing logic. That number can be a guess, a temporary placeholder, or an internal estimate that gets replaced once the distributor feed is live. We also do not need to remind readers how rarely early “price leaks” like this end up matching the official MSRP.
What both listings have in common, they lack basic identifiers from the manufacturer or official distribution channels, such as a proper product code and an EAN/UPC. If those details are missing, we usually ignore any pricing or spec fields attached to the listing, because the page is often just a placeholder.
Czech retailers often price Valve hardware higher than Valve’s own store, and the gap varies by shop and by region because of VAT and reseller margin. Even basic comparisons using Steam Deck pricing on Czech storefronts show that local listings can sit well above Valve’s direct pricing, which makes any early Steam Machine figure hard to treat as a real signal. As an example, 13999 CZK is €576, 37% higher than official MSRP (€419).

Still, this rumor has already spun out of control while Valve has not announced official pricing yet. Any real numbers will have to come from Valve, and until then, listings that look like placeholders should be treated as such.
