But now I've made more work for myself, cos the motherboard(s) I had in mind won't support SATA 6Gb/s and the one that does that I think will be ok uses a different socket configuration for the CPU.
Subject to me checking them out more closely, either of these CPU's look like they would do and are close to the i7-950 in speed. See end of this post for suitable motherboards.

I reckon 650W is on the slim side for the power supply, but that's your call. Having said that it's not so much the wattage but the efficiency (or lack of leakage/wastage) that matters. A 650W PSU that rates highly is better than an 850W PSU that rates poorly, as long as it's meeting it's basic power requirements to start with.
If you wish to go for the WD Caviar Green series then I'd recommend the WD20EADS if it's used only as storage and has no real performance requirements to speak of, other than not being crap
For the motherboards, prob best to let you wade through these yourself, a lot of them are similar but be sure to check the specs and make sure has at least 1 x SATA 6Gb/s on board and more than 2 x SATA 3Gb/s on board. USB 3.0 ports are the other thing to check for, HD stuff looks pretty good across the range.

If you end up not bothering with anything requiring SATA 6Gb/s hard drives then it's back to the i7-950 CPU and Intel Socket 1366 motherboards.
Aaaaaand I'm spent.
