I wanted to get an office machine for the office that would be able to handle simple web browsing and handle remote login to servers - this meant it had to be low noise and tiny. The Beelink U55 with the i3-5005U is just enough to do the job.Power-wise, the i3-5005u is on par with the late desktop core 2 duos of the late 2000s, which is more than enough for most tasks. It handles videos fine. The unit does not draw a lot of power and very little heat, but be aware there is a fan and it is conservative with its fan speed settings so you may hear it ramp up (but in an office environment with a fan or window open, you will not notice it).Additional storage can be added if needed. Please be aware that with the device running Windows 10, your device will run very slow on the first day as it will most likely be downloading updates and installing them, which slows down the computer as a whole. To check on this, go to the Windows icon > Settings > Update & Security > Windows Update; yours, if similar to mine, will have a large list of updates as soon as you connect to the internet.If you need a simple web browsing machine or something for an office, this would be great as it is low powered and small.
