Quadra 630 board compatible with Performa 6200 case?
Posted by: David Cook on 2022-05-17 20:29:01
The Quadra 630 / LC / Performa series seems to have the same case, accessories, and motherboard connector/size as the Power Macintosh / Performa 6200 series. Does anyone know if the cases/motherboards are interchangeable?

They fit nicely. I just haven't had the courage to plug in the power yet.

The Quadra 63x/Performa 63x/Performa 52xx/Performa 53xx/Performa 62xx/Perform 62xx cases are all supposed to be based on the Quadra 630 form factor and should be interchangeable. Have a look at this post on Lowendmac:

Take heed, this subject has come up before so use the search function.

Form factors are pretty much identical across desktops and AIOs. FuglyTowers have a second slot in the PCI era, so that's a differentiation you're not facing.

PSU, Case and Harness cannot be assumed to be compatible when swapping boards around. Due diligence required. 😉

LEM articles are a blessing and a curse, depending upon many factors. I'd take any Y2K article there with a block of salt. The info available around these parts in the last decade is a far more reliable source, if not always correct. Nothing is perfect.

Yes they mostly do. x400 and x500 boards do require 3.3V which isn't provided by earlier PSUs, but that's not an issue here.

Yep, but not necessarily. ISTR someone finding a harness differential in upgrading a P5200 AIO to Q630 in the last year or so?

The NuBus ->PCI architecture shift on the 630 drawer machines changed things dramatically on both harness and PSU fronts.
