@82mhz it works surprisingly good, especially without a Desktop Environment. I thought it would take longer to boot with the slow disk, but it's actually very reasonable. Around a minute, give or take.
Going without a DE is also a nice experiment for me. I'm pretty comfortable in the terminal and for what it's worth my WSL daily driver is also headless. But this is the first machine where I don't have quick access to a browser to look something up. I'll try getting one of these minimalistic terminal browsers set up next.
Oh and another surprise: this thing actually had built-in WiFi... and it's stupidly slow. 😬 But I can just attach my phone via USB and share the WiFi from that.

@mikegrindle @srgower @82mhz @jake4480 performance-wise it's surprisingly okay. I've even installed LXDE in the meantime and experimented with Lynx as a terminal browser and Dillo as a GUI browser.
The only thing that's thrown me off is that there only seems to be a years old version of Hugo that can no longer compile my blog. I'll need to check if there are still newer versions around for 32-bit systems. 🤔
I don't want to compile it myself. If push comes to shove, I'll just use my homelab as a poor mans CI and glue something together from Bash and rsync to make that somewhat comfortable.
So far I've spent a lot of time getting things set up, rather than writing, but hopefully that'll change in the next few days.
