Sell your tech now. Windows 10’s sunset and AI PCs are really boosting demand. List on AEM Labs Marketplace with lifetime free seller accounts and 0% listing fees, plus UK support.
With GPUs hitting ÂŁ1,200 and CPUs topping ÂŁ400, new-gen builds have priced many UK consumers out of the market. Instead, the community thrives on second-hand hardware - a culture rooted in affordability, value cycles, and sustainability through reuse and right-to-repair.
CoreWeave and OpenAI have expanded their partnership with a new $6.5B contract, bringing the total to $22.4B in 2025. The deal supports OpenAI’s Stargate project, relies heavily on Nvidia hardware, and raises questions about concentration and regulatory scrutiny in AI infrastructure.
Nvidia’s $100B OpenAI deal promises 10GW of AI compute power by 2026. The company insists GPU supply for gamers won’t suffer, but with such massive demand on the horizon, many fear a repeat of past shortages. Is this the start of an AI-first Nvidia era, and what does it mean for PC gaming?
Nvidia’s $5B stake in Intel isn’t just about faster chips. It’s a U.S. chip alliance forged in the shadow of a trade war with China - a lifeline for Intel to stay competitive, and a move that could reshape how PC gamers and data centers power their systems.
PC parts don’t just lose value.. they cycle. New launches push buyers toward older GPUs and CPUs, reducing supply and raising demand. Here’s why second-hand components stay valuable and how sellers can prepare them for resale.
Windows 10 dies in Oct 2025... but you can continue using it safely. Spend a 6 minute read to learn what it really means, what Microsoft's ESU offers, who qualifies, and how to protect your system while others rush to Windows 11.
Microsoft have pulled the plug. Support for Windows 10 ends in 14 October 2025. Truth be told, not every PC can run Windows 11. Here’s the truth about Microsoft’s requirements, why TPM matters, and what to do if your PC is left behind.
From fake components to disappearing sellers — pre-owned PC deals can go wrong fast. In this post we share 5 true-Reddit horror stories of buying or selling used hardware, plus practical tips you can use to protect yourself every time you trade.
When we built AEM Labs, we knew the marketplace itself was only part of the bigger picture. Buying and selling hardware is important - but the real strength comes from the community. That’s why we’ve built several spaces where you can connect, learn, and have a say in what we do at AEM.
