If I was getting an online integrator (I'm thinking digital storm) to make this PC for me, and they have a three year parts and labor warranty, good customer service etc..., how much do you think is a reasonable price for the above computer? And what good price / performance changes would you make? And would I need a more powerful PSU if I was ever thinking about getting another 4870 and crossfiring?

Thanks

Looks great.

Manufacturer warranty still stands. If a part craps out, send it back to them. Store warranty has the fastest turnaround.

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX%u2122 technology in dual mode)

I like the build. Although I have no idea what the cooling solution is. I have a similar build built in an NZXT Tempest case and Nvidia gfx.

Good luck!
