I don‘t know if this is the right place to ask, but is this an OK build for a first start in selfhosting? Is there anything obvious I could improve? I‘d mainly run Nextcloud, Immich, some Docker containers and smaller web applications and cronjobs.
You must log in or # to comment.
Depends on the docker containers but it’s way overkill than you might think.
Since you’re starting it may be worth looking into used office PCs like the thinkcentre from Lenovo or other brands(no tiny or ssf since they don’t have to room for drives). They often offer good perfomance for the price and the power consumption is not too high.
I run a lot of containers in my homelab, which consists of an OrangePi (similar to an RaspberryPi 5). It works surprisingly well, and was only (at the time) $250 for the board, case, and emmc drive.
16GB of ram is a bit low for the load you’re planning. That can work, but Nextcloud and Immich are pretty hungry for memory. My immich instance right now is using 7GB of RAM and nextcloud uses a bit over 4. I have the hardware to give them pretty much all the memory they want, so those are not absolute minimum amounts, but I wouldn’t try to run either with less than 6GB allocated memory on my load (few users, about a terabyte of data on both).
With 16GB you can pretty much forget using ZFS, but that’s not a big loss. LVM works just fine and with thin provisioning you can use snapshots too just fine. Bigger SSD/NVME for drive cache would be good. And of course all-SSD setup would be nice, but that gets expensive pretty fast. Second ethernet port might be nice to have, depends on how you’re planning to build your setup. Otherwise that hardware looks pretty good, altough I’d search for something second hand. CPU is most likely a bit overkill for what you need, I have Xeon E5-2620 v3 @ 2.40GHz and it’s running on around 10% load most of the time.
7GB for immich is wild, my instance with 2TB of photos is currently using 811MB of RAM. What’s eating it all?
Have you checked while it’s running all the ML tasks on import? Mine uses a good chunk of RAM while that’s running.
It’s a full VM, so OS and docker creates some overhead, but before I upgraded the server it ran on far less resources and specially big imports were painfully slow. Also that’s just the number from proxmox console, so there’s likely some cache included, but stats show that the VM pulls over 10G every now and then with shorter spikes over 20GB of consumed RAM.
As I mentioned, it can run on way less, but it feels a lot more responsive when it has enough resources.
I just ran an import of only a dozen photos and it did go up to 2.3GB usage. I knew containers were more lightweight but I didn’t think a VM could get that bad. Hopefully it’s reporting a sum of virtual or assigned memory space and isn’t actually hogging that much in physical ram.
Immich itself is running on docker, so it’s the same than every other setup. For me it just makes more sense to run that on a separate VM than keeping all the docker containers in a same operating system due to backups, manageability, access control and so on, even if it costs a bit of memory to run a full operating system. Biggest consumers on the host process list are immich-api, postgres-processes and immich. Actual used memory is around 2,5GB for the whole system with ~5GB on buffers/cache.
But I often import hundreds of raw photos at a time from DSLR and/or 4K video footage from my drone and processing those takes quite a lot of memory. With less memory and slower drives the whole thing crashed when importing bigger batches to out of memory erros, but I suppose it could run just fine with even less than 4GB of memory, if the usage pattern is just to upload photos from your cellphone in a relatively slow pace.
I made a very similar build almost 2 years ago.
I did not like the Jonsbo N4. The HDD temps were bad. The case amplified HDD noise and was a pain to build in. I used a Silverstone SFX power supply. I had two of those PSUs fail in less than a year.
After the second expensive SFX PSU failed, I decided I did not want to buy another. I changed cases to the Fractal Design Node 804 and bought an inexpensive ATX PSU. I have been much happier with my build after those changes. My HDD temps dropped by about 10 degrees Fahrenheit. The case is much quieter and I was impressed by the quality.
You can get Ryzen 5650G Pro from ebay that will support ECC. Just make sure it’s not vendor locked.
Obviously you’d need to adjust mobo, not sure if Gigabyte supports ecc. Asrock was pretty cool with ECC.
I’d recommend using eficient procesors as well, so with ryzen with grafics and efficience it’s GE at the end. I recently switched ryzen 5 5500 for ryzen 5 4600GE (because 5500 doesn’t have efficient variant) and the consumption halved (- 30Wh). And both were/are basically idle with very low loads.

Yes it will be fine. Much will depend on what OS you will run and in turn how you want to do storage. NAS drives might not be necessary if you going to use software defined storage. If in your budget consider a CPU with more cores for virtualization and docker.
Overall nothing wrong with that configuration. But if you really get into all the awesome stuff you can self host your two constraints are RAM and CPU cores.
The NAS drives are here because they are from an old NAS which only uses a cheap dual-core Intel, has 2G of RAM, and boots from eMMC. So anything would be an upgrade…
Your server looks fabulous, and I’m not discouraging you from pursuing it in the least. However, if I may draw from my own personal experience and what I am currently running, it may give you some ideas. Currently, I am running 53 containers on a Optiplex 7020 SFF with the i7-4790 and 32 GB RAM. Just checked and it’s load average at this moment is: 0.47, 0.60, 0.73. Meaning it’s pretty much in an idle state except for logging in just now. Grand total cost was less than $200. It consumes about $8 USD/month.
Unless you’re going to get into selfhosting heavy AI models, most stock PC, office discards, etc built in the last 10 years will do just fine for a homelab, with a little love like some additional RAM or a dual nic card. Immich and Nextcloud will probably require a bit more than 16 GB RAM running together. I don’t run Immich, but I do run Nextcloud and it does just fine with the above set up. No lags, stutters, etc.
How much do to pay for electricity? I’m running an I5-3470 and it costs about $17.50 USD/month, at $0.23 per kwh, the stack of 3.5" HDD’s pushes up the power consumption a fair bit though
I pay around $8/month USD. Now, there are factors involved. One, electricity in my locale is relatively cheap. In addition, I have solar. To contrast the Optiplex 7020 SFF, I used run the same containers/content on a Dell T320. It cost $40/month USD. which still isn’t an outrageous expenditure for someone with another type of hobby. Some of my other hobbies, like creating music, those prices climb steeply, rapidly. Last count I have 48 guitars, several banjos, 8 bass, an oud, mandolin, 4 full size Korg synth keyboards. three violins, and amps out the yang. So $40/month was peanuts, but I wanted something that wasn’t such a hog. Plus the heat dissipated by the T320 was significant, and that is passed on to your AC bill as well. The 7020 is much quieter, energy efficient, and produces very little heat. Win, win.
I have that same case in black, overall very similar setup. I like how it looks, but if I would change one thing in my server it would be the case. It’s quite a hassle to work inside of, and for its size, only being able to hotswap 4 HDDs is very little compared to other cases you can find.
It’s not bad by any means, but you can get better
I would probably go Intel with iGPU for the transcoding and acceleration for Immich. i3-14100 is fast and cheap.
Otherwise you definitely have far more CPU power than you’ll need for those apps so no worries there.
It is but ddr5 is not cheap
It supports DDR4 if you buy a motherboard that supports DDR4 too.
Follow up question: Do I need a separate CPU cooler, or is the boxed Wraith enough? And how loud is it? I can’t really find info on that.
Wraith is fine. I have mine installed and it’s dead quiet. If you don’t like the noise, you can always get a 15-25$ USD aftermarket cooler, brands like ThermalRight and Cooler Master come to mind.
So long as you’re using the spinning rust hdds, the noise of the CPU cooler won’t make much difference. Mind you, this PC will be a bit too loud for the living room like this.
Just about anything is OK for a server, I use whatever hardware I get from work thats being decommissioned.
The biggest limit I see is the ram. Depending on what you spin up and how, it’ll be the tightest budget per service.
If you’re already going for spinning rust hard disks, why limit yourself to the 3 TB ones? IMHO, these days, spinning rust only makes sense at 8 TB+ per disk.
I have them at home and as such don‘t need to spend money on them.
Story of my life
2 of my 4x 4TB spinning drives are portable. 2 in mirrored raid, and on-site backup, and an off-site backup. If you don’t have it on 3 drives across two sites, you don’t have it. 5400RPM is fine as long as you allocate some of that NVMe as a cache for it. Keep all high-transaction stuff like databases, thumbnail caches and indexes on the NVMe drive. Going to 7200RPM just increases power consumption and noise, and reduces reliability.
The other specs seems fine, but I personally upgrade my desktop then take the old CPU, RAM and motherboard to use for my server.
Immich and Nextcloud run fine on my 2015 Core i5 with 16GB RAM.
How do I do that with the SSD cache? Everyone just talks about it, but I can’t find any documentation…
I’m using bcache, and I’m using btrfs as the filesystem on top of it. I’m not sure that the way I’ve done it is considered best practice anymore. The discourse online is a mess because the landscape keeps evolving.

Might be abit much but double your ram if you intend on using a lot of apps
I agree. The most limiting factor is still memory for me. And I’m max out currently of my motherboard (128gb).
Recently thessecond limiting factor is actually cpu. But that is due to my gitlab runners.
how are you using 128 GB? Genuinely curious because I run over 20 services with only 8 GB
- I run 50+ websites
- MariaDB instances
- PostgreSQL instances
- Docker containers
- Mbin, Nextcloud, GitLab, GitLab runners, gitea, bitcoind, fulcrum, grafana, prometheus, influxdb, Synapse, Angie, telegraf and various other services like fail2ban etc. etc.
All optimized for performance and fine tuned as well, eg. lets say you run mariadb vs how I run it:
innodb_buffer_pool_size = 8G innodb_flush_log_at_trx_commit = 2 innodb_log_file_size = 2G innodb_log_buffer_size = 32M innodb_max_dirty_pages_pct = 90 innodb_io_capacity=5000 innodb_io_capacity_max=20000 innodb_read_io_threads=8 innodb_write_io_threads=8 query_cache_type = 1 query_cache_limit = 2M query_cache_min_res_unit = 2k query_cache_size = 128M tmp_table_size= 128M max_heap_table_size= 128M [mysqld] max_connections = 200 character_set_server = utf8mb4 collation_server = utf8mb4_general_ci transaction_isolation = READ-COMMITTED binlog_format = ROW innodb_file_per_table=1 # Increase open files based limits.conf value open_files_limit=65535Same idea for Postgresql… You can run “postgres” or… actually run postgresql in production correctly like:
shared_buffers = 6GB work_mem = 20MB maintenance_work_mem = 2GB maintenance_io_concurrency = 200 max_worker_processes = 14 max_parallel_workers_per_gather = 4 max_parallel_maintenance_workers = 4 max_parallel_workers = 12 synchronous_commit = off commit_delay = 300 checkpoint_timeout = 30min max_wal_size = 60GB min_wal_size = 4GBActually now that I check your username I think I have seen your instances before, though it seems like your website is down at the moment. But thank you for service to open source !
nah its not down… maybe you use a VPN.
I do. Do you block all VPNs? Or is it just rate limiting?
I block some misbehaving data centers. Which are often also used by VPN providers. So it’s more collateral damage.
No I fully block some data centers not just rate limit.
FYI: I’m a noob myself.
Looks fine, but if you’re looking to mess around with a first build then you could go cheaper. Secondhand hardware would save you money, especially since older hardware is great for server use. At least you’re saving money with AM4 and DDR4.
Some thoughts:
- I went with an Intel CPU for Jellyfin transcoding.
- 16gb ram is enough to start and I host tons of stuff with that much, but the more ram the better. Having 2 more ram slots for future expansion would serve you well (but not essential).
- Faster networking would be better. Your mobo has 1 gigabit LAN. Again not a deal breaker. You can add faster networking yourself later.
This guy makes great videos, but you have to be careful to not overcomplicate things or chase specs that pro home server guys want that make no difference to noobs.
