You can get them with 8GB RAM and a 250GB SSD for around $200 (CAD) (7050). Throw in a 2 TB NVMe (M.2) drive in it and you're ready to install node software that wants two drives like nostr:nprofile1qqsp4za5duapejf2g0exeu354jzuh8fe9fevldxhsqztk9hhtteurxgpz3mhxue69uhhyetvv9ujuerpd46hxtnfduq3jamnwvaz7tmwdaehgu3w0fjkyetyv4jjucmvda6kgqglwaehxw309ahx7um5wgh8wctvd3jhgmmxwdshgmmndp5jucm0d52al5wf or nostr:nprofile1qqsw5t3us9xs3gmclzjm37hvk2yy6pv9t96utjjttsj794hexc5x79qpzdmhxue69uhhwmm59e6hg7r09ehkuef092q0zz.

I like the first two options because the OS goes on the smaller drive and all the data (wallet, timechain and lightning channels) goes on the 2 TB drive. If the OS drive blows up, you just reflash the OS drive and continue on (after a small catch-up sync of the timechain).

I prefer the Micro version of the Optiplex, since it barely takes up any space, but there are SFF and desktop size versions as well.

Far superior to running a Pi and about the same price.
