"However, the Celeron N4500 processor is where things get a bit tricky. The dual-core Celeron struggled to keep up, even with relatively simple tasks. Running more than a few windows, with messaging PWA apps open, and music playing resulted in noticeable lag. The 8GB of RAM does help a little but the Lenovo Chromebox Micro struggles to keep up with even my most daily workflow. And with only 32GB of storage, you’ll need to keep your downloads and app installs in check, too.
Compared to other Chromeboxes on the market, the Chromebox Micro may not be the best fit for someone who wants a desktop workstation. On the plus side, the fanless design ensures the Chromebox Micro remains completely silent, which helps keep the internals clean and dust-free, especially since it might be tucked away behind displays or monitors."
