2/9/2022:
I have a 2015 Dell XPS desktop. It was a pretty high end machine when I bought it, plenty of RAM, large drives, gaming video card. Last year, the C: drive and video card both went. I replaced the C: drive with a ssd drive, but decided that a new video card was too expensive on a machine this old. The machine has three drives and a total of six TBs of storage. I have been using the machine mainly to sync with Dropbox without taking advantage of its feature to store the files only in the cloud. I do that on my laptop, which has much less storage. This way if I need to leave Dropbox, or it left me, I had full copies of my files.

Recently, there were Windows alert that my Windows 10 software was out of date and prompted me to upgrade. I tried several times. The updates fail and Windows undos the update. Today I tried to make the machine an Ubuntu machine, but the installation threw a bunch of errow followed by a black screen. I think the machine is done. I would like a machine, however, that function in a similar way, with full download files synced with Dropbox.

It looks like Dropbox can be installed on a Raspberry Pi. Maybe a Pi with a couple of external drives in a dock with maybe a RAID would be just as good for this purpose as a new desktop. Worth exploring.
