Hey,
I'm working on building a compact, efficient, and budget-friendly home server to centralize my scattered data and host a few lightweight services.
Currently, my data is spread across multiple hard drives, and accessing it is a hassle. A while back, I set up a home server using an old netbook running Debian and a few Docker containers. It was a fun Linux learning experience, but not a long-term solution (its RAM can’t be expanded beyond 2 GB, and its CPU is too weak). So, I guess it’s time for an actual dedicated server machine!
Budget: Around €500, including storage (I’m in Europe, btw)
Requirements:
- Centralized storage for data, photos, and phone backups
- Run lightweight containers for web services like Immich, Paperless-ngx, Pi-hole, and custom services I’ve developed
- Occasionally download Linux ISOs (I use and delete them; the whole *arr stack would be overkill for my needs)
- No need for virtualization (so no Proxmox, TrueNAS, or Unraid); a plain Debian install with Docker should suffice (or maybe I could use OpenMediaVault)
- No closed OS: I’m not interested in Synology, QNAP, or similar. I want full control to install and customize my OS
Goals:
- Low power consumption: ≤10 watts idle without HDDs would be ideal (this is my number-one priority)
- Low noise
- Compact size: space is limited, so it needs to be small (I also don’t need a huge case for just a couple of drives)
Ideas:
- DIY Option (ASRock N100DC-ITX):
- CPU + Mobo: ASRock N100DC-ITX (~€138)
- RAM: Kingston ValueRAM 16GB 3200MHz DDR4 Non-ECC CL22 (€32.99)
- SSD (for OS and containers): Patriot P320 128GB NVMe PCIe Gen 3x4 (€15.99)
- PSU: LEICKE PSU 19V, 4.74A, 90W (€19.99)
- Case: Sharkoon QB ONE (€50)
- Total: ~€257
- Concerns: Will the 4-pin connector on the board be able to power two HDDs? ASRock includes a cable to power 2 HDDs in the package, so it should be fine, and I don’t plan on adding more drives
- DIY Option (ODROID H4+):
- CPU + Mobo: ODROID H4+ (€196)
- RAM: Crucial RAM 16GB 4800MHz DDR5 Non-ECC CL40 (€48.90)
- SSD (for OS and containers): Patriot P320 128GB NVMe PCIe Gen 3x4 (€15.99)
- PSU: LEICKE PSU 19V, 4.74A, 90W (€19.99)
- Case: ODROID H4+ Case Type 4 (€44.90)
- Accessories: 2x SATA data and power cables (€14.00)
- Total: ~€340
- Concerns: I’m unsure about reliability and updates, and with 2 HDDs, it’s out of my budget
- Prebuilt Option (AOOSTAR R1):
- Specs: N100, 16 GB RAM, 512 GB NVMe
- Total: ~€238
- Concerns: Power consumption might be higher than the ASRock and ODROID boards; I’m unsure about its reliability and updates; I've read that it can get noisy and heat up
Storage:
For storage, I’m planning to use two 4 TB HDDs (Seagate IronWolf, ~€120 each) in a mirrored configuration. I’m considering ZFS for its compression, deduplication, snapshots, and bit rot protection. However, I’m unsure if I really need RAID since I’ll perform regular backups.
Questions:
- Which of these options would you recommend?
- Are there better hardware options within my budget that meet my power/noise/size goals?
- Do you have other suggestions for hardware or software I might have overlooked?
Any advice or feedback would be greatly appreciated!
Thanks in advance :)
I believe you should buy second hand hardware for that. Can't beat the price and you've tons of gamers and offices trying to get rid of perfectly good hardware for what you're trying to do. I mean a 8th gen i5 CPU will most likely be idle or in low usage most of the time.
I would say to buy i5-8500T or more recent (because you can run a full machine on 8W on that). You can either go for a micro ATX motherboard with that and RAM second hand OR pick an HP Mini ProDesk with the same CPU, both options will be about 130€. Check this example.
The thing with the Minis from HP is that they come with everything, NVME, power supply, ram and ready to go. Most of those more recent machines come with 2x NVME + 1 SATA + USB-C.
If you're comfortable with taking the board out of the case you can place it anywhere and add a M2 to SATA adapter on both NVME slots for about 22€ each and have like 12 SATA HDDs connected to it. If you don't want mess with the hardware you can get a USB DAS for your disks, since it's all USB-C you will not notice any performance impact.
Those machines will outperform your CPU pick by a lot while being cheaper and power efficient on idle.
+1 on this idea, going to toss in my recommendation for an AMD 5600g second hand. Its basically a laptop CPU with built in GPU that handles my jellyfin transcoding without issue and has a super low idle power rating if you pair it with a quality, small PSU.
Yeah, laptop CPUs are low power, after all they're configured to run on battery with Windows. :)
