I needed a quiet server fast enough to run some development tools at home. I currently run them on my laptop that has an i7-7600U CPU. The CPU of this box, i3-8130U, is only about 10% slower than that, which gives me confidence that it is fast enough (you can search for "7600U vs 8130U" to see for yourself).I bought 8GB of DDR4 RAM at 2400Mhz with 260 pins, installed it in the box, installed an m.2 2280 SSD SATA drive, wrote a Ubuntu server installation ISO image to a USB drive, plugged it in, connected keyboard and monitor and powered up. It booted from the USB drive without me needing to do anything else. I installed Ubuntu 18.04 in no time and now this little server is already working for me.The biggest uncertainty in this whole process is how loud the fan is. I can happily report that it is very quiet. Even at night you can barely hear it.I am a happy customer and I may buy more.ASUS, please correct the description and make it clear that this box doesn't come with either RAM or storage. That can eliminate the fear of many people who are looking for a perfect little box like this to buy.[Update after 4 months of usage] I have been using it as a server. I set up its BIOS to return power state to the last state when power is restored so that the server can reboot by itself after a power outage. It's been running for 4 months without a single issue. It's fast and quiet, perfect for my purpose. I am sure I will buy more of this series in the future. PN61 is an update on this model.
