If you have a 3D printer you can design and print one. Did that many times in the past. There are also a lot of pre designed models available on Thingiverse, Printables etc.

Else you can look at Aliexpress or so for a closed one and cut the holes yourself. Or try one from another motherboard.

Many backplates from roughly the same era fit with several motherboards. I have used same IO plate with different motherboards.

If you can access 3D printer, that is one way. You can find designs in printables or thingiverse. There are some that are designed specifically for certain MB, but then there are blanks and meshes, where you can cut or CAD your own holes.

I buy spare backplates from Ebay. You just need to find one that matches the layout of the motherboard components. Most of them are pretty standard.

This is a standard ATX layout which all early ATX motherboards were shipped with, so any standard plate will work.

If you go the 3D print route, I have this one in my collection:

I've been lining the backs with foil tape lately and it makes them feel more realistic (and actually shield).

These are indeed some of the most common backplate, not too hard to spot, even in a large pile.

Thanks for the suggestions everyone. Sadly, I don't have access to a 3D printer. Yet. It is something I'm interested in though as I do character modelling and sculpting. If it is fairly standard and easy to find, that's good. Reassuring. I'll take a look on eBay and AliExpress and see what I can find. 😀

Hmm. Can't say I've been having a lot of luck finding one. Most that come up have a lot of holes for the various ports/jacks. Finding one for this specific model, which only has seven, is proving tricky.

This one?... https://www.ebay.co.uk/itm/126713871485 (not my listing)

You utter legend! Thank you. 😁

I guess my searches were too specific. I was typing in the motherboard model followed by I/O plate. Or Abit I/O plate. :p Less is more, I guess.

Only snag though, is that first image doesn't appear to be assigned to any particular model. Going through the ones that are available in the drop-down list, they're all the wrong ones. So I'm wondering if that first image is to a model that's sold out. I'll try reaching out to the seller.

bit expensive but what about this one

Ooh. Nice find. Thanks. Yeah, it is a bit pricey for what it is. I'll see if I get a response from the other seller first, but if not...

Okay, so I finally got around to getting a replacement plate, however, as is the case with me, I'm easily confused and struggle with the most basic of tasks. ^^; I got a similar plate to the ones linked, but paid much less. However, I'm struggling to fit the damn thing. Newer machines seem to have them inserted from the inside of the case so they're facing out. I get the impression with this setup, that they're inserted outside of the case. However, the left side doesn't appear to line up and I can't get it to snap into place. The right side I can. I'm starting to wonder if this case needs a very specific I/O plate...?

If you're sure it's the right size you can use a small hammer to force it into place. It's what I do when the fit is difficult.

However that looks like it came out of an OEM system. Why didn't you just buy a plain metal generic plate instead of that? Those fit everywhere.

ETA: I see it has part number 5065-6701 which almost certainly is HP. (I have HP stuff with similar numbers, e.g. Netserver LH-4 I/O board is 5064-7070.) HP are notorious for using non-standard stuff in their computers.

That looks like it should be inserted from the inside of the case, not the outside.

Remove everything from the case and then try to install it from the inside.

I've never seen an I/O plate that is fitted from the outside. It sounds like bad design because it will just pop out if the case is flexed.

Ah. Bugger. 😕 I figured it would be one size fits all if it had the same number of port holes. Not to mention the ones I was originally linked to are quite pricey for what they are.

Okay. I must admit, I really couldn’t be bothered getting everything out to insert it, but if that’s what’s required. 😅

Yeah, the IO plates are always put in from the inside so you have to remove the motherboard to do it.
