I've read it's possible to fit a atx mobo and psu in an at case I have a large tower at case and I wanted to know how to do it can it all be done from the home or do I need to take it somewhere or buy some special parts or something?

ATX boards should fit any mid or full size tower.

I have never heard of nor can find reference to an AT case.

The limitations are usually on the downsize such as Mini ATX or Micro ATX.

A standard ATX board should fit any mid or full size tower.

Can you link to or describe in more detail what an AT case is?

An AT case from what I know and what I've read is a different form factor and it has different voltage AT uses 5 and atx uses 3.3v or something like that but I want to do is take an AT case and fit my atx board and psu in it it's a large tower so I think it will fit but the case has an AT style power switch. Which I've read is different from an ATX case because it uses solid contact or something and ATX uses momentary. here's a link to pretty much what I want to do.

Also the ATX case doesn't have a cutout for all the things an atx case has it's just has one slot for the keyboard and the expansion bays. on the back.

but I can cut that out I just want to see if my PSU will work with the case and my mobo.

Thanks for the link. I now see that form factor:

I don't have anything to add beyond the ideas in your link but perhaps others will.

Just to mention that new ATX cases are relatively inexpensive and can be quite unique as well.

http://www.xoxide.com/allcases.html just for example.

I can't buy one now unfortunately and I'm impatient plus I see it as a challenge it's been done before I just didn't want to spend 5 or 8 hours trying to figure it out. Haha.

I need pictures of the inside of an AT power switch and how to convert it to an ATX power switch I've got the switch apart just not sure where to go from there.

When I first started building PCs, they were all AT cases and power supplies. Then ATX came along in the late 90s and gave us some cool stuff like letting Windows turn them off automatically (anyone remember the "You can now turn off your computer" message from Windows 95?!). I remember from those days that there was no way whatsoever that an ATX PSU would fit an AT case or vice versa. Unless you wanted to get out a big tool kit, including a drill, a bolster, a file, a junior hacksaw and a soldering iron, and start "customising" the case design, making holes for the PS2, USB, serial and parallel ports that aren't there in an AT case and then re-wiring the power supply switch AND the power connector to the motherboard, which is entirely different. Only to do all of that and then throw it all in the bin because you've wrecked the whole lot.

For the sake of £20 or so, I can't imagine how you could have so much spare time on your hands that you would want to do all that instead of go out and buy a cheap ATX case with the PSU already fitted!

yeah I thought I did but now I'd rather just buy one.

sounds fun lol

regarding the switch, i have (well had) an ATX motherboard and power supply but used (and will use again) a latching keyswitch (i do turn it on then off to get my PC on though)

good thing is, if it freezes, i can just turn the key and leave it (rather than keeping hold of the switch

I remember that!!! we had a 95 PC for 6 years!!! think we got rid of it just before xp came out!! lol
