Hey!
I’ve decided that it’s time to finally get something resembling an actual server for my home setup, and I was hoping you folks could give me some pointers (given the current prices).
My current set up is just my old laptop with 2 external hard drives plugged in - one is the regular portal USB HDD, another is 3.5 HDD plugged via powered enclosure (ZFS and LUKS on both). I want to switch that for something relatively small, but extendable, as I want to add more disk space in the future. I’m selfhosting Plex, Immich and Navidrome, and occasionally some multiplayer games like Valheim. I’m not planning to use Proxmox or TrueNAS/whatever, I mostly just plan to throw Debian on it and spin everything in Docker.
I looked through some guides on https://selfhosting.sh/ and on Reddit, but that just got me more confused, as everyone keeps suggesting Optiplexes and NUCs, but I don’t get how to combine that with 20TB+ disk space while ensuring the disks are secure and well powered. Plus my understanding is most of those mini-PC’s/refurbished workstations use regular DDR3/4, whereas I was hoping to get ECC.
Should I go DIY route, or is there something I could get as a solid enough base to expand in the future? If DIY is the answer - what mobo/cpu/case should I get? My ideal budget (for everything excluding hard drives and maybe PSU since I have one lying around) is ~500 euros, but if paying a bit more would mean a substantially better deal - then I’d be OK with that. I’m in Berlin, so if you know any good local markets - that’d be great too.
Thanks!
UPD: So, I’ve learned of the existence of bargainhardware, which drastically changed my approach and so far I’m leaning towards https://www.bargainhardware.co.uk/dell-poweredge-t330-tower-server
(Yes, I understand it’s loud and more power-hungry than some of the other options out there, but it does tick all of the boxes…)


So my home lab has been raspberry pi’s of varying shapes and numbers for a few years. Recently my single floor condo flooded so half of my place has been ripped up and so much crap has been stuffed in the other half I decided I should get around to planning out a more complete home lab setup. Money is a bit tight but I called up my ISP and it turns out my internet package comes with two static IP addresses so I decided to snap those up. I will be building up a firewall with a pi 5, I will continue to use a pi 4 I have running HAOS, as I try to get out of all the ecosystems. I was born into the Apple ecosystem, the first computer I remember using was some old Apple DOS computer, so breaking out of that walled garden is going to be tough but it helps that Tim Apple gave Trump a golden Apple plaque so it hurts less with every service I turn off.
Any who because I have had a lot of time to make plans and game through my plan with AI I have decided I am going to self host my domain and email (Simple blog and 200+ annonomized email addresses) on a pi 5 that will be the third pi 5 after my firewall the first pi 5 will host things like immich, nextcloud, and the other things it is already doing one of those other things is pihole and that is where my DHCP is currently, I am on the fence about moving it to opnwrt or not. The Second pi 5 after the firewall also hosts a secondary pihole as a back up dns and all my high seas (like sonarr.tv) things and jellyfin.
To top it all off I am going to get another pi 4 with a hdd and I will ask for it to be hosted some where to do off site back ups.
