I’m mostly worried about energy usage. The CPU’s TDP is 65W, the CPU in my current server’s TDP is 35W.
It does have a few advantages over my current setup:
Is this a good option or is there a better option? I’ve also been considering using an external drive enclosure with software RAID, but I heard that could be unreliable.
I was worried about the power usage when I first started using my old gaming CPU for a home server (i7-4770k). I bought a kill-a-watt, ran it plugged into that for a month, saw that it was using pennies worth of energy per month and never worried about it again.
Unless you’re pegging the CPU at 100%, it’s not going to be pulling the full 65W. As far as maintenance fees go, the cost of replacing a single hard drive will likely overshadow your energy costs.
Pro tip: keep an eye out for hard drive deals on black fri. And I recommend doing a burn-in run on any new drives when you get them to push them past the initial failure window of the bathtub curve (I used badblocks. Took nearly a week for the initial run, but I found one bad drive and was able to RMA it immediately instead of finding out the hard way).
How high are you electricity prices? Mine are €0,40/kWh.
I don’t have my bill in front of me, but for my state it looks like mine’s effectively around €0,10/kWh. So yeah, more expensive for you.
I built the server I’m using now over a decade ago, with much worse specs, for way more money.
This will last you a long while depending on your requirements.
What are the use cases? More RAM is nice but could be overkill if you’re bottlenecked by CPU, and if this is for running a few simple VMs or as storage then you may not need much of this.
RAID is generally a good thing but don’t get complacent, follow the 3-2-1 method. I.e. you might be better off saving the cash and using a backup script to push stuff you really care about to the cloud, and pay for cloud fees vice hw.

To expand on that: Redundant drive setup and backups serve completely different purposes. The only overlap is in case of a single disk failure, where RAID (or similar) may save the data.
Redundancy is all about reducing downtime in case of single hardware failures. Backups not only protect you from data loss in case of multiple simultaneous failures, but also from accidental deletion. Failures that require restoration of data almost always involve downtime. In short: You always need backups (unless it’s strictly a local cache, and easily recreatable), but if you want high availability, redundancy may help.
3-2-1-rule for backups, in case you’re unfamiliar: 3 copies of important data, on 2 different media, with 1 off-site.
Use case is a few simple VMs, Nextcloud, storage, maybe a minecraft server and probably something like Jellyfin later on.
This will be fine. But assume you’ll want to swap out the hard drives in the future for more, larger, NAS appropriate disks.
What’s the storage capacity on this motherboard? I know with their office PCs, you only get 2 SATA ports and typically only a single PCIE slot so you’re forced to choose between a GPU or LSI SAS card. I have a huge media library so this was one of my primary concerns when I specced mine out years ago.
A more modern processor probably has better power efficiency. But this one should support features like turning off some of the cores or throttling down when not needed.
You could also see if you can get one with lower power consumption, like even the 6700T.
Used processors are quite reasonable on eBay. I got one with a lower TDP and it actually benchmarked higher than my previous CPU (came with my used Dell workstation).
But with Intel changing their socket every couple generations, you’re talking about a new motherboard too if you want to upgrade.
The lowest option is the i3-6100 which brings it down to $236.95 in total.

I'd buy a Dell Optiplex 5060 for about $200 off eBay and you'll get a i7-8700
It seems to only have capacity for 1 drive.
Sorry for the late reply. You can replace the optical drive with a 2.5" HDD or add a sata PCI-E card since your not using the GPU slot in this case. My personal setup uses an NVME for the OS (DietPi), and two 6TB external HDDs on an Optiplex 5060 SFF.
TDP doesn’t have much to do with idle power draw, that’s more based on the age of the CPU and specific type (standard, U, or T skus)
Exactly. Just as a real world example for OP, my home server has an i5 7400 with the same TDP. At idle the whole system draws around 10.5W, measured from the wall.
Get a 10th/12th Gen processor so that you can transcode powerfully if you’re intending to use jellyfin.
Wow it didn’t even click in my head that this is a 6th gen Core. How is OP speccing out a custom server using 8 year old parts?
I always dissuade anyone from buying Intel for any purpose. A backdoored CPU undermines your security and privacy to an unacceptable degree.
Why would PSP be better than IME?
PSP allegedly does not have internet acces so it can’t call home while IME does.
A backdoored what? As if AMD is any more or less secure.
I didn’t see anyone else say this, but 7200 rpm disks are way louder than 5400. Where my server is it would be annoying, but if it’s in a closed room somewhere you’ll be fine.
The “designed for 24/7” thing is a myth. Yes, some server/enterprise parts have a lower failure rate, but it has nothing to do with 8 hours a day vs 24.
Also, my setup is almost entirely the cheapest consumer drives available, and I’ve never had any significant failure rates outside of the one bad supplier. If you are seeing anything like that, you should examine your setup. I suspect you either have cooling issues or (more likely) vibration that’s causing premature failures.
I have never known RPM of a drive to affect its noise level. The fan(s) will be far more significant in noise level. Most drives run pretty quietly, though some can get noisy during I/O, like my HGST Ultrastar He6 drives.
Also, without knowing the model, I wouldn’t say they’re not made to run 24/7. But even on desktop drives, it’s rarely run time that kills them, it’s start-stop cycles. Everything will be fine, but one day you’ll shut it down and some drives won’t spin up. That’s why power outages can be deadly to an old server.
If RAID is what you’re after, don’t mind the premium for SSD storage and have available 5.25" bays, I highly recommend 5.25" mobile racks. The one I’m using is a a cheap 4 drive one, but if you want something more premium there is always ICY DOCK.
I doubt a 5.25” rack will fit in my closet but thanks for the suggestion 😄
Mobile rack is just what these things seem to be called. Basically it’s just a cage that fits multiple 2.5" drives into an CD/DVD drive bay.
Depends on what you’ll be using it for. If your use case is a simple NAS with shares , torrents and whatnot it is probably overkill. If you plan to transcode video then it might not be .
Seems decent but depends on your usage. Memory could be a bit excessive unless you’ll actually have a lot of simultaneous users. I’d also look into the features of the integrated graphics card. If you’re doing some streaming a low cost GPU might give you better options for hardware decoding/encoding.

If you are planning to use it as a jellyfin or other media server, look for 8th Gen or later Intel. They have Intel quicksync that provide hardware decoding.

Why 8th gen? Wikipedia and Plex say quicksync was added in Sandy Bridge.
AlphaAutist@lemmy.world 1 year ago
8th gen is when support was added for HEVC I’m pretty sure
ChrisLicht@lemm.ee 1 year ago
QuickSync is available on earlier gen machines. I have 7th gen with it.
Buckshot@programming.dev 1 year ago
I’m running Jellyfin on 6th gen i3 and quicksync works fine.

You make a good point, but OP’s pick is still a really good choice. In early 2020 my old desktop became the new home server: i7-6700K w/ 32gb ram. It’s been going strong every day since. Unraid with Jellyfin, pihole, HAOS, and like 20 other containers running. I generally serve untranscoded 4k hevc videos locally, but I tossed in an old geforce 900 series for both on the fly transcoding as needed (honestly, it’s rare if ever) and for tdarr.
