Corrupt Win7 installer? Error 0x80070570

I'm attempting to install windows to a 40GB SSD and I continuously receive the error 0x80070570. My first thought when I got the error was that it could have been an issue with the file itself. So I redownloaded it and still got the same error and from there I've tried nearly everything listed in other threads relating to this issue. Here's a synopsis of everything I've done thus far.

Start:
Removed old hardware, replaced with new mobo, cpu and gfx card
Downloaded Windows 7 Home Premium from microsoftstore.com
Using the Microsoft supplied tool I created a bootable USB flash drive with the ISO
Powered the new hardware on for the first time resulting in a clean boot with zero errors
Booted to Win7 install, ended up with Error 0x80070570
Redownloaded the ISO, Remounted it on the flash drive
Attempted install, still errored
Repeatedly attempted the install sometimes resulting in a freeze of the installer but usually the same error message
Tried installing on my other SSD
Cleaned and reseated RAM and Slots
Did a secure wipe of both SSDs and retried install on both
Attempted install with the ISO burned on a DVD using low speed...same error
Tried reburning multiple times with the same error each time
Ran 5 passes of memtest on both ram sticks in all possible configurations. 0 errors

After all of these steps I still cannot complete an installation. The install errors out at different points of the "expanding" step each time.

Finally in a spate of desperation I tried using the same media (2 DVD attempts, 1 USB, and then just the ISO directly downloaded from microsoft to the system) to install windows via Parallels on my Macbook Pro...It still errored! Does this mean that the file on Microsoft's site is corrupt...? What on earth should I do at this point?

I'll poke around on there to tonight. I didn't see one when I was there last though. You just pick your file type and click a download button. I think there might be a few freeware type things out there (did a quick google from my phone).

With the file still not working on my Mac I may attempt to install with a different version of Windows 7. I have an Upgrade version available as well as an "Anytime Upgrade" key for Ultimate. I don't know how I can get the DL files for it though.

I'm currently trying to install Home Premium (with the intent to upgrade it to ultimate with my key later.)
