Got this on sale for $270, which is an absolute steal. Even still, the full price (~$330) is a bargain, too.Despite what the manufacturer has stated in the comments/Q&A, this comes with a vacant bay for a 2.5" hard drive. It also includes the necessary parts to install the 2.5" hard drive (mounting bracket, a connection/adapter, and a ribbon to connect it to the mother board).The rear/bottom plastic cover can be removed by unscrewing the 10 screws on the bottom, and GENTLY, with a PLASTIC prying tool, pop the cover off. You have to start at a corner and then slowly/carefully work your way around. Even with great care, I lightly marked the case in a couple of places.UPGRADES:I added a 500 GB HDD (regular, spinning hard drive). Search Amazon for "2.5" 500GB" and take your pick - anywhere from $20-$40 will do the trick. If my instructions above are not enough, Acer's own YouTube channel has a video you can follow.I also added a 4GB stick of RAM to bump the total memory up to 8GB, which is more than enough for this laptop - you're not going to be playing any crazy games or doing any heavy duty stuff like video processing anyways. The specs on the RAM that you should conform to are DDR4 2666 SODIMM 260-Pin (as noted by the manufacturer in the Q&A). Someone mentioned the ram is running at a lower Hz, but best practice would be to buy RAM that matches the stick of RAM the computer comes with.Also, do a search on taking Windows 10 out of "S" mode. S mode is a security mode that only allows you to install apps from the Windows Store, which effectively prevents you from inadvertently downloading malware. As long as you use your best judgement when downloading apps (and/or install the antimalware software of your choice), you shouldn't need S-mode.Took all of 10 minutes to uninstall any extra bloatware that came on the computer.Voila, for ~$330 and about 30 minutes of your time, you effectively have a ~$550 laptop.For the price, the processor is very snappy, and the screen is extremely sharp. The keyboard feels very natural & is satisfying to use.
