Can I replace the mainboard to put more RAM in than the current max of 2GB? It would also then be prudent to replace the processor. The case is of a high quality, which is why I think it's worth salvaging.

Is it a nightmare to replace the :)therboard on such an "OEM machine"?

Thanks for any help in advance, as ever. :)

you dont have to take pics, just tell us the model of you motherboard - it should be printer right on the motherboard in the biggest letters there (usually near the ram or cpu)

cheers

OEM boards don't generally denote their form factor on them. Even my ASUS P5Q Premium doesn't say so on its PCB even though it is an Extended ATX board.

Model of motherboard found:

PTGD-VX (as you'd expect, it's a Sony OEM board)

I'll post pics in two minutes of the look of the case (i.e. where the power supply is located etc) as I think the layout will prove to make things difficult, as it wasn't designed to be mucked around with.

Thanks for help so far :)

Looks like a regular micro-ATX board to me. Is the faceplate over the ports on the back removable? If so, motherboards include one that just snaps on. The pinout of any buttons and LEDs on the machine might be more difficult though, and you might have to trace where all the wires go and add new connectors to them. The PSU could also be an issue if it's old and don't have the outputs needed by modern motherboards.

it would be pretty hard to explain how to replace a motherboard on that kind of case, since it is so rarely used... and that is the weirdest location to put in a power supply that i have ever seen! o_O

also, im pretty sure you can still replace the motherboard, you just have to be careful with the form factor

I too was hoping it was a faceplate but its the PSU (see other pic).

Yes. I mean to the left of the PSU where all the ports are. If you look at the bottom of that, it looks like it might be removable. I don't see how the PSU is an issue other than it maybe being too tight a fit for a large cooler.

I have the Sony RA 820G. If your system is like mine then it is liquid cooled. The way the cooling element sits over the cpu even after you have removed the spring mounted screws it restricts you from lifting the motherboard straight up and out of the case. The case seems to have been riveted around the internals once installed.

I obtained a perfectly matching replacement case from another RA series model with a good psu and a bad board and I was hoping to swap my good board out of my rusted (aka Hawaiian gold encrusted) case with a bad psu into the nice cleaner case. Once the board is unscrewed you just can't get it out of the case. I came to this forum hoping to find a clue as to what rivets to selectively drill out to effect a board swap.
