At the moment I don't have spares when one of my boards die. But I'm on the lookout for a spare Gigabyte GA-7IXE and Epox 8RDA+, IF the price is right.

Yeah, I have spare boards.

Yes, I have a spare board for my current PC, a Core2Duo build that I made of second hand parts in 2018. I thought it was a good idea to have a spare board, so far however I haven't used it.

Sort of. It took me four attempts to get an MSI MS-6168 V2 board (i440BX with Voodoo3 onboard) that would reliably run a Tualatin and do so at 133MHz FSB. I still have the best of the rest too, but if anything happens to the primary, I'll have to drop the clock.

Yes, but not by design - some purchases have just worked out that way for various reasons (price, opportunity, rarity etc). For those that don't have an exact "twin" I have enough functional duplicates to probably cover most scenarios, except maybe for some off-the-shelf barebones systems and my quad opteron boards.

In fact TOO much for my wife taste

Since all my system are Complete IBM desktop is hard to find a spare mainboard. but if i find a good price i will take some on ebay

Yes, I have one backup for a number of things. No more than one though.

I have a general supply of spare parts. Unless a motherboard is proprietary, I don't usually worry about the specific model of board.

For parts that are proprietary I do keep duplicates on hand. If something breaks, having a working version to compare with makes repairs a lot easier.

My two main retro computers both have backups but other systems for miscellaneous tinkering don't. I guess it depends on the degree of loss/acceptable downtime a failure presents.

I don't have a spare for most boards. If my daily runner (Z170 w/ i7-6700K) dies, it'll motivate me to build an X99 system I've been putting off, with an 18C36T Xeon. Should be much more powerful, even if it's a lower single thread core speed.

I do have a spare PVI-486SP3, but thinking of testing that and putting it up for sale

I do not but if prices and supply could go back to 10 years ago I probably would.

I don’t, at least not intentionally. I certainly have a few doubles just from the different bundles of parts I’ve bought, but that was never the plan.

If one of my rare boards dies, I’ll certainly mourn the loss, but really I scratch my nostalgia itch just by fiddling with different stuff. So almost none of it stays as a complete system anyway.

Edit: Whoops, I didn’t finish my thought before submitting. The one system I keep whole has a 440bx board, and I definitely have a few more of them kicking around, so if it dies I can quickly replace it with something similar at least.

For many platforms, yes, I have spare boards. Not necessarily the same model but sometimes I do have a preferred model or family or chipset. P3B-F of P4C800 are good examples, partly because of the adapters they support.

I keep spare duplicate machines and at least two similar chipset motherboards if cheap enough.

Many spares... not intentional - just a hoarder 🤣

I nearly had a spare in form of a donation of optiplex 780 tower with good motherboard, few years ago, which I promptly rebuilt my almost faulty 780 motherboard in a 760 Optiplex chassis that I built years ago which was my main PC from XP, 7 then windows 10. Did this, originally I didn't know was faulty from ebay purchase this due to meager finances. I needed to upgrade from Athlon XP PC.

Both have plastic panels swapped to recreate a correct Optiplex 780 tower and also bonus replaced the missing 3.5" panel. 😀

Faulty motherboard was clock intermittently changing either way to any time, forward or past time on XP and 7, battery was already replaced few times. Windows 10 self corrects the time so didn't see the issue.

Cheers,

Nope, my thinking is hardware in storage can still go bad.
I'd rather spend the money on another build.

Like others I do have a stockpile of HDD's, optical drives, etc pulled from pc that come my way

No dupes, but I'm considering one for my current retro computer given that the other Slot 1 motherboard that I have is a Gateway one whose only ISA slot doesn't work well with any sound card and can't handle VIA C3 CPUs. 🤣

For the now inactive and stored Socket 7 computer using a Gigabyte GA-586ATV motherboard: DFI G586IPC as a fallback.
