Hi,

My Unraid server has been running since ~2012 and, aside from adding HDDs now and then, its the same motherboard/cpu/ram.

I have been wondering how long it can last and if I should proactively plan on building a new one. There is nothing wrong with it and no signs of failure but at 13 years is it statistically bound to happen soon?

thoughts or advice?

thanks

Well, let's consider Voyager I. That computer has been running for fifty years now! You can read a bit about it here:

IF you want to know more Google is your friend....

I would not just replace a working MB, CPU and RAM because it is old. Yes, it may fail tomorrow or it may last another twenty years. I would wait until the system can't do what I want it to be able to do, (Plus, at this point in time, Components costs are rapidly increasing due to the demand being created by AI. Hopefully, this is just a hiccup and prices will drop again as more capacity comes online.)

Usually hard drives are first to go, depending on thermals a cpu, ram and graphics card would be next. Hard drive have a known MTS (Mean time to failure) which averaged 3-5 years.

Some processors (if they were nott hurt in production or had poor microcode over the years (both amd and intel have had some faults) theses usually outlive the machine. Motherboards depending on production and Thermals last generation and chipsets of current needed hardware vs current gen markets which usaly last 3-5 years on average... but the motherbaord can essay out live 30 years. (I still have comdor and win 95 systems that still boot to this day...)

so an average current gen system should last 10 or more years Deeping on expected workload(a mining sytem due to thermasl may hurt hardware and not last as longs per exampe), thermals and hardware specs mater here. Enterprise hard drive have higher mean time. and cheaper hard drives if not using or pushing for full performance can often outlast and live longer then the estimated MTF.

Voyager 2 is a good example. I usually look at the super computers and clusters of systems that cycle though server systems over time....
Alot of systems that can't really be bought down and are specked for redundancy / uptime like government systems and healthcare systems.

I still have a few Intel 5th gen systems that run unraid and do fairly well. (15 year old systems) that still work great today with VMS, plex, dockers etc...
https://en.wikipedia.org/wiki/Intel_5_Series

that said its all about what the processor can handle now in terms of chipssets and microcode instructions... like windows 11 realy wants the "popcnt" instruction chipset capable processors...

new ai sytems with TPU/NPU built into the CPU... which may make older tech obsolet due to software restraints. Looking at nvidai with deviecs hit EOL. Looking at the nvidia gtx 780 v400 seres drivers.
This will not run in todays kernels... event eh linux open source won't touch or load them... Nothing worng with this great xp era G card. But it will no run unraid, transcode or other use case with unraid withough goin into a older OS... the 780 still works but the software is newer then the hardware. thus its time to upgrade into curent / next gen of Graphic cards. Hardware when taken care of can last Many years.

This is the answer

My desktop and server systems usually like the Ship of Theseus. They never really get replaced, but over time end up has nearly every component being replaced either for an upgrade or repair. The only original parts left in my main server are the case and drive cage, the flash drive and a few cables. Everything else was either added or has been replaced.

Redundant redundancy

My build was a Gigabyte Z68A board - so just a basic consumer grade MB. Very surprised it has lasted. In reply to a question above - yes it still does everything I need! no issues with running a few dockers and/or a few streams.

I was a bit worried about the costs going up which also made me wonder about building a DDR4 build.

However guess I'll keep the Z68A going for awhile longer!
