Hello. My mom has an old Pentium 60 which just isn't cutting it anymore. I have a bunch of spare parts, which include an ATX 250w PS, ATX motherboard, PII 233, ATI Xpert98, and so forth. My question is this. Can an ATX Motherboard fit into an AT case? This is a full tower Gateway case. I know I will have to cut out the back plate since the serial/printer ports don't line up, but other than that, do some of the screw holes line up for the motherboard. The Power Supply looks like it will be any easy fix, but I'm not so sure on the motherboard. Thanks
ATX motherboard in AT case?

I don't think it will work, but there are motherboards that are made to work with both ATX or AT like the Asus P5a-b. You would also need a different type of power on switch for ATX power supply. I bought a very decent mid-tower from a PC shop, where the guy removed the power supply. It only cost me $20 without the power supply.
It will work. I just ported an Abit BP6 (dual celeron motherboard) over to an old Gateway 2000 full tower case. Like you stated, you will have to cut out the backplate. The holes on the motherboard will line up with the holes on the csae just right. You will need some plastic spacers for about 3-4 holes as the case may not have screw holes there.
Once my motherboard was screwed in, the PCI and ISA slots lined up fine with the slots in the case. It's a really nice full tower case that I didn't want to go to waste. One problem you may have is that the ATX power cord may not be long enough to read your motherboard. Mine barely does, but if I didn't, I could have purchased an extension from Frys Electronics for about 10 bucks. I also had to purchase an ATX power switch for 2 bucks.
A good full tower like the Gateway tower goes for about 90-100 bucks nowadays and you won't get the satisfaction from knowing that you had to drill and saw some parts to make it work.

Yea, I just ran into the power switch wall. No one in town has an ATX switch. If I did get one, what do I do to change it? Right now, there is a big black cord that goes directly from the Power Supply to the Power On Switch. If I got one that went from the MotherBoard, how do I know if it will fit ?
That's where the AT/ATX standard comes in. The switch mountings are identical, pull the old AT switch out and replace it with the ATX switch.
There are more differences then the 120v cord. The ATX switch is a momentary contact which means that it is only conducting while you hold it down. The AT switch is a ordinary on/off, it holds a state until you change it.
If you can get to something like Frys you may be able to find ATX backplates. Use one of those as a pattern for the hole you need in the back of your AT case, then fill it with the backplate.
Before you go to all of this work be sure that your case is worth converting.

Man, I live in the Ass Crack of America-small town Iowa. I don't have crap around me. However, I called a computer buddy who works at Gateway who says he has an ATX power switch. I'll update later.
I searched for 6 months.....But I did find an internet oufit

Radio Shack doesn't have the switch?
If you take an AT style switch apart and remove its latching lever (small bent metal rod), it becomes a momentary switch.

Damn, if you lived somewhere near me, I'd send you one. I have 2 of em sitting in a box doing noting. Anyway, hope your conversion works out fine.
Go to Radio Shack and get a "momentary Push-Button Soft-Feel Switch", Cat. No. 275-1566. You will have to solder the switch to an old mainboard jumper with wires you have laying around (or make one). I converted my old Macase AT tower-works great.
Just use your reset switch as the power on button. I did the same thing with my monster AT tower. Put a 300Watt ATX PS in there and chopped up the back panel as mentioned. Not elegant, but hell, the way these guys chop holes in their cases for fans and such, what's the difference?
