I do not believe all the old things need replacing.
I see stil the C00 card without USB. If you change the lot, why not add those things the G series has ?
The power supply in my 861 got changed for free a few years back, so i assume it will not be very expensive. It does not look very complex, so more or less standard parts.

The backplane look just passive from what i saw when i peeked inside when the distributor upgraded my from V2 to V3 and V3 to V4
