While I love Raspberry Pis and have a few older ones, it's a shame that the latest ones were very hard to come by and far exceeded the $35 price point.

I was looking to upgrade to a Pi 4 a while back but prices were outrageous or it was sold out completely. I eventually discovered tiny form factor PCs.

I bought some used Lenovo Tiny ThinkCentres (which are about 10x more powerful than a Pi 4), off eBay for ~ $70. I upgraded the Ram and SSDs and they are quite capable, low power units!

So to anyone looking for a low power computer to run Linux, consider buying used off eBay. You can get some pretty good deals on used hardware that's more capable.
