"Good for someone slow, checking email, like grandma maybe!"
The AIO is extremely slow due to its weak laptop motherboard, CPU and limited 4GB slow DDR3. Can only hold 8 GB in the single slot. Very few USB ports either and forget about external monitor, USB 3.0, or other more modern connections. The unit is also very small, needs to be on a stand to see it at head height, unless you are very short like my grandmother as mentioned in the title. I would recommend this only to fill the (small) niche I guess for which it was intended. Slow, slow, slow...
The OEM exact screen, brand new, worked perfectly for a F555L-AB21! Very hard to find screen with most others being sold not the correct one. Order this one and you will not have to return it!

A+ for HP i5-8400 Optane Assisted Desktop
Very fast and sleek professional looking computer with a small footprint that has all the features one would expect from a mid-grade yet inexpensive, Intel 8th generation desktop with 16GB of Optane memory. Make a full image backup as soon as you complete your setup and everything will be ok. This is in case the optane has a problem caused by a sudden loss in power (i.e. assuming you have no battery backup) and all should be well. Otherwise, you may be looking at sending the unit back to HP since the OS is often loaded into the Optane. However. this seems to be true of all computers with Optane-assisted flash memory. Don't forget, make that recovery image!
