You can go far below $300 with very little practical performance compromise, but I wouldn’t even look on Amazon with memory prices being what they are lately. Get an old DDR3 era Optiplex desktop on eBay, throw a $25 Quadro P400 in it for transcoding, and transfer your existing SSDs over. Tons of eBay listings have 2-4 day shipping. With DDR3 you can easily get 16GB of RAM for like $30 if it doesn’t have enough already. Avoiding DDR4/DDR5 will save a ton of money so it’s essential to buy used.

The SSDs and hard drives for the array are by far the most expensive part. I’ve been using an underclocked and undervolted Ryzen 1700 in my server for 6 years now and have zero complaints around CPU performance. I did eventually need more than 16GB of RAM last year, but the only outright failures I’ve had are on the various component’s fans.

We don’t buy great value milk anymore. It’s time for a few days but consistently spoils far faster than any of the other options for us. So it’s not really great value unless you consume a lot of milk.
