About This Site
What this is
This Site is a structured, English-language database of compatibility information for manufacturer desktop computers (Dell, HP, Lenovo, and similar OEM desktops). For each supported desktop model, we compile — from official specification sheets and other documented sources — which discrete GPUs the published specifications indicate the machine accepts physically and electrically, and, for each of those cards, what the VRAM calculation outcome is for a set of local large language models (LLMs).
The goal is simple: if you own, or are considering buying, a used or existing OEM desktop and want to add a GPU for local LLM inference, you should be able to look up your exact model and get a sourced, confidence-rated answer instead of piecing one together from scattered forum threads.
What we don't cover
This Site does not cover memory (RAM) or storage (SSD/HDD) upgrades, printers, or general product reviews. We also don't publish ranked "best of" lists or article-style buying guides. The Site is a reference database, not a review or editorial publication — see our Methodology page for how the data itself is compiled, and note in particular that we do not physically test hardware.
Who operates this Site
This Site is published by a company established in Japan. We do not put our corporate name, our address, or the name of our representative on the Site; our Privacy Policy explains how you can obtain them.
Every verdict here rests on a published specification, cites the document it came from, and carries a confidence grade; how those grades are assigned, and what each one means, is set out in our Methodology. No part of the database is contributed, reviewed or sponsored by a manufacturer or a retailer, and no manufacturer or retailer has any influence over a verdict.
Why this Site is in English
The Site covers desktops sold by Dell, HP and Lenovo and graphics cards sold worldwide, and its readers are mostly in English-speaking markets. It is written in English and cites English-language retailers. It does not link to, reference, or share any account, branding, or content with any other site or project.
How we make money
This Site earns commissions through the Amazon Associates Program and the eBay Partner Network when readers purchase products through outbound links. See our Affiliate Disclosure for full details. Compatibility verdicts are never influenced by which retailer or product pays a higher commission — see our Methodology page for how verdicts are actually determined.
