My Q6600 is starting to struggle and we've had more and more problems with reliability, more blue screens of late than I can remember for a long time. It may just need rebuilding, but I'm thinking of upgrading. 
I'll need a CPU, board, and ram. I'll be carrying over the ssd and raid 1tb, 4850 graphics and antec sonata with 500w psi.
I've looked at i5 2500k, stock or mild overclock, 8gb ram and would like to add in a sealed unit water (antec/corsair) CPU cooler. Looking at around £400 budget. Would love an i7, but don't think it will fit within budget, though I could keep existing 4gb ddr3 to keep price down and upgrade ram later.
It won't be used for gaming. It will be used for multiple office based applications for wor lass, media server to the tv via media box and network to phones and iPad. I'll also use it for photoshop cs5.
