Same. Everywhere i looked was upwards of 150-175, every time i looked. Fucking things were pushing 300 by some resellers even. I found a lot of 5 used Optiplexes, for just over 100 bucks or so on the bay. Gigabit ethernet, modernish celeron chips, and more. Theyre faster than a pi5, only lack some hardware encoding/decoding. Even run x64. One is a low budget seedbox, one is my klipper box for my 3d printer, one is a pi-hole/fail2ban server, one is used for most of my SDR dongles/ rf antenna, and the last one sits unused as of now.
I dont do anything with GPIO pins really, so the loss of those was NBD. If i come across something like they ill use an arduino.
