Selfhosted

Running a bunch of services here on a i3 PC I built for my wife back in 2010. I've since upgraded the RAM to 16GB, added as many hard drives as there are SATA ports on the mobo, re-bedded the heatsink, etc.

It's pretty much always ran on Debian, but all services are on Docker these days so the base distro doesn't matter as much as it used to.

I'd like to get a good backup solution going for it so I can actually use it for important data, but realistically I'm probably just going to replace it with a NAS at some point.

It's not absolutely shit, it's a Thinkpad t440s with an i7 and 8gigs of RAM and a completely broken trackpad that I ordered to use as a PC when my desktop wasn't working in 2018. Started with a bare server OS then quickly realized the value of virtualization and deployed Proxmox on it in 2019. Have been using it as a modest little server ever since. But I realize it's now 10 years old. And it might be my server for another 5 years, or more if it can manage it.

In the host OS I tweaked some value to ensure the battery never charges over 80%. And while I don't know exactly how much electricity it consumes on idle, I believe it's not too much. Works great for what I want. The most significant issue is some error message that I can't remember the text of that would pop up, I think related to the NIC. I guess Linux and the NIC in this laptop have/had some kind of mutual misunderstanding.

I'm still interested in Self-Hosting but I actually tried getting into self-hosting a year or so ago. I bought a s***** desktop computer from Walmart, and installed window server 2020 on it to try to practice on that.

Thought I could use it to put some bullet points on my resume, and maybe get into self hosting later with next cloud. I ended up not fully following through because I felt like I needed to first buy new editions of the server administration and network infrastructure textbooks I had learned from a decade prior, before I could continue with giving it an FQDN, setting it up as a primary DNS Server, or pointing it at one, and etc.

So it was only accessible on my LAN, because I was afraid of making it a remotely accessible server unless I knew I had good firewall rules, and had set up the primary DNS server correctly, and ultimately just never finished setting it up. The most ever accomplished was getting it working as a file server for personal storage, and creating local accounts with usernames and passwords for both myself and my mom, whom I was living with at the time. It could authenticate remote access through our local Wi-Fi, but I never got further.

4 gigs of RAM is enough to host many singular projects - your own backup server or VPN for instance. It's only if you want to do many things simultaneously that things get slow.

I'm sure a lot of people's self hosting journey started on junk hardware... "try it out", followed by "oh this is cool" followed by "omg I could do this, that and that" followed by dumping that hand-me-down garbage hardware you were using for something new and shiny specifically for the server.

My unRAID journey was this exactly. I now have a 12 hot/swap bay rack mounted case, with a Ryzan 9 multi core, ECC ram, but it started out with my 'old' PC with a few old/small HDDs

You can do quite a bit with 4GB RAM. A lot of people use VPSes with 4GB (or less) RAM for web hosting, small database servers, backups, etc. Big providers like DigitalOcean tend to have 1GB RAM in their lowest plans.

Got all my docker containers on an i3-4130T. It's fine.

your hardware ain't shit until it's a first gen core2duo in a random Dell office PC and 2gb of memory that you specifically only use just because it's a cheaper way to get x86 when you can't use your raspberry pi.

Also they lie most of the time and it may technically run fine on more memory, especially if it's older when dimm capacities were a lot lower than they can be now. It just won't be "supported".

3x Intel NUC 6th gen i5 (2 cores) 32gb RAM. Proxmox cluster with ceph.

I just ignored the limitation and tried with a single sodim of 32gb once (out of a laptop) and it worked fine, but just backed to 2x16gb dimms since the limit was still 2core of CPU. Lol.

Running that cluster 7 or so years now since I bought them new.

I suggest only running off shit tier since three nodes gives redundancy and enough performance. I've run entire proof of concepts for clients off them. Dual domain controllers and FC Rd gateway broker session hosts fxlogic etc. Back when Ms only just bought that tech. Meanwhile my home "ARR" just plugs on in docker containers. Even my opnsense router is virtual running on them. Just get a proper managed switch and take in the internet onto a vlan into the guest vm on a separate virtual NIC.

Point is, it's still capable today.

My NAS is on an embedded Xeon that at this point is close to a decade old and one of my proxmox boxes is on an Intel 6500t. I'm not really running anything on any really low spec machines anymore, though earlyish in the pandemic I was running boinc with the Open Pandemics project on 4 raspberry pis.
