Where do you get an i7 875K for only $200? The best I've seen is $299 after rebate.

I went to the gigabyte board on tweaktown and the solution was don't use the marvell ports, use the intel ports. WIth the intel ports I got like 581 mb/s. I'm pleased at the performance but not at the fact that somethign i paid for isn't working.

The problem with the P55 chipset and USB3/SATA3 is that Intel both has not put these technologies on their own chipset, nor have they accounted for the level of bandwidth these technologies need to connect externally.
Essentially, in order to electrically connect the extra chips needed for these two interfaces, the board maker either has to a) jack them into the CPUs PCIe lanes which are intended to be used by the GPU, which is the case of Gigabyte boards, and has the effect of dropping the available lanes for the GPU to 8 from 16, or b) take up all of the PCIe lanes on the southbridge, which is a disadvantage because the southbridge's connection to the CPU (there is no 'northbridge' on P55, it's the CPU) is slower than the combined bandwidth of the connections common (generally NEC) next generation controller chips are capable of, and is used by Asus.
It's a no-win situation, and exists because both because Intel kept an aging bus design for P55 between CPU and chipset, and because they did not endow the CPU with any extra PCIe lanes for use with devices aside from the GPU.
If it were me, I'd go with Asus' solution. You keep compatibility and don't reduce the speed of the GPU bus. Although I doubt either limitation will make a difference for you.
Also, while a next gen (G3?) Intel SSD might use SATA3, don't expect it to affect the performance of a mechanical drive more than the 1% due to increased cache transfer speeds. Also, don't expect there to be a huge useability difference with devices that do use SATA3 effectively. It's going to take more than one more generation of SSD controllers to make a real difference out of >300MB/s bandwidth from hard storage.
For your GPU, a cheap 5770 is probably the way to go if you're looking no further than SCII. I don't have any problem with the game on my GTX260, which is slightly faster.
I believe that cases are intensly personal. I would suggest that even the cheapest setup that would fit your selected components would do, especially if you intend to throw it away after use. Cases are just a system of mounts, and you lose very little outside of overclocking and noise control by going with a cheap solution, assuming that it doesn't collapse in on itself or submit you to arterial bleeding.
Thermal paste won't really matter unless you're going for an overclocking record. Use what comes with the HSF.
