Can you fit a modern motherboard (along with the appropriate modern components) into an old computer case?

I have a rather ancient computer from the mid 90s that doesn't work. I was wondering if you could completely change its insides, so that it only LOOKS like a piece of crap but can perform just as well as today's computers.Can you fit a modern motherboard (along with the appropriate modern components) into an old computer case?
Yes u can.Can you fit a modern motherboard (along with the appropriate modern components) into an old computer case?
Technically, it should be able to fit in. The only problem, is that the power switch on modern motherboards is actually a button that flips an electronic switch, rather than a physical switch you flip, and old computers use a physical switch. This means that even replacing the power supply unit would be a problem. One possible solution, might be to connect the reset switch to the power connection on the MOBO, but I don't know for sure if that can work.
If it is an AT style case then no, you can't put any modern parts in it. If it is a newer old computer that uses the ATX for factor, then yes you can. It mainly depends on the size of board that you want, meaning if it is a big tower, then you can put any ATX board in it. If it is a mid-size tower, you can only put a micro-ATX in it. But, as long as it is a standard ATX type board it will work perfectly.
Depends on the motherboard and the case. They make both in all sizes and shapes. The biggest problem I've had with switching motherboards into a different case (even a fairly new one) is hooking up the on-off switch and indicator lights. Every mobo seems to use a different style of connector.
even if it can fit in there, you most likely will not be able to mount the mobo to it. get your old tower, measure it, and tell the dude at the pc will this mobo fit in my tower. but even then these new mobos require specific towers cuz they got holes in specific spots where you screw them into the tower. the tower needs to have the same hole alignment. not every mobo fits into every tower even if the mobo itself can physically fit into the tower. get it?
You should be able to if the case follows the standard ATX form factor that's been around for ages. However, older cases tend to be more cramped and aren't quite designed for newer hardware so you might have issues or at the very least be lacking in some features. A descent steel case only costs about $50 anyway so it's definitely worth looking into a new case.
if the case is an ATX case, then it should be very straight forward, but if its one of those manufacturer specific designs from that era, then you are better off getting a modern case
as long as the measurements fit then yes. any case will do.
