Right this big case I got has a turbo button on it and a 3 digit LCD display.
Any idea what they're for and wil they work with a normal ATX motherboard?

On some they were posh and showed you the speed on a led which you could set by jumpers so it meant nothing. On later ones it did nothing but put on a yellow light

In the early days of IBM clone PCs, a lot of clone manufacturers introduced motherboards that used faster system clocks than a genuine IBM machine. However, this caused timekeeping problems for some versions of DOS, some programs and also some expansion cards, so the Turbo button was invented to allow you to switch the system clock between standard IBM PC speed (4.7 Mz for an XT or 10.0 Mz for an AT if I recall correctly) or high speed. The display was typically used to show the clock speed, on some machines it would just display 'Hi' or 'Lo'.

It was used in the days of 8080/8088/486DX processors that ran at clock speeds of 4.77 or 8Mhz (yes MegaHertz, not GigaHertz) where you could switch between the speeds. It has no use today except where you can map the key to a windows function / shortcut.
