I am several months into the self-hosting journey and I feel I have outgrown my Pi 4 B 8GB. I’m only running around 3 dozen containerized services and it seems to struggle to keep up. But I’m not sure of the best bang for my buck. I’d like good, long-term performance, but I don’t really have a grand lying around for a Lenovo Tiny or Dell Optiplex or ASUS NUC. I’m thinking of buying an SSD to boot from, but will this even help much? For $350-500, could I make a more cost effective homeserver upgrade?
I recently replaced a pi4 with an intel n95 based mini-pc and it’s been an absolute joy. I moved a few of my services and VMs over from the main server. It runs my Homeassistant via HAOS in a VM significantly faster than the pi4, another VM with access to the IGPU runs a 4k dashboard feed into my video distribution matrix, a few containers for simple things like MQTT and Adguard Home (like pihole) and it has room to do more.
The whole computer with 16gb of ram and 256gb SSD cost about the same as a pi4 8gb did when the shortage was at its worst.
The other option of course, is a cheap older optiplex, for under $200 you can get quad core sky lake or kaby lake generation processors, 16gb of ram and room for a couple of SSDs, a bulk storage HDD and a couple of low profile PCIE cards.
