Final build post: (2nd try....)
Okay, it's all put together and running... Unfortunately, the drivers that seem to work best with this set of hardware are the Windows 8 Customer Preview Default drivers + Catalyst 12.3 display drivers... Under Win8 C.P. & that driver setup, FAH runs very consistently with the GPU client running 2,800 ppd, and the SMP client running work units with consistent frame times.
However, this is the 'final' build & is running Windows 7 Home Premium 32bit w/SP1. I've tried all different combinations of drivers, 100% Gigabyte supplied drivers, AMD Auto-Detect drivers, 12.3 Catalyst driver pack, 12.4 Catalyst driver pack. I guess my next step is to let Microsoft Update find & install drivers for me... FAH runs, but... GPU client refuses to fold... SMP client runs, but frame times are all over the place... from 2 1/2 min to 25 min per frame. WU's that ran flawlessly & consistently at 2 1/2 min per frame in Win8 C.P. with drivers as noted in first paragraph, but that also performed identically to my current situation when downloading & installing Catalyst 12.4 driver pack.
Anyway, it's up & running & folding away for now, I'll play with it some more this evening after I get back from my 2nd viewing of The Avengers - in IMAX-3D this time!!! I'll probably do a clean install without installing driver updates & let Microsoft Update find & install drivers that they think will work...
I played around with overclocking this APU, it goes nicely up to 3.2GHz, then not so nicely beyond that. So I figured, if it'll do 3.2GHz as is, I can drop the voltage & lower temps at stock speed. Dropped CPU voltage from 1.387V to 1.362V, FAH temps dropped 2C, and computer power usage dropped from 122W to 118W.
Oh, and I had to void the warranty on my RAM... Damned heat-spreaders were too tall to use with the Scythe, so I had to pull the spreaders off & put shorter ones on. If only there were one more payday before Mothers Day

However, this should not present any problems. The RAM is rated to run at DDR3-1600 @ 1.65V with Latency timings of 9-9-9-24. It will be ran at DDR3-1333 @ 1.5V with Latency timings of 11-11-11-28 (Auto setting in BIOS), so it shouldn't need those huge heat spreaders anyway, plus the 140mm fan on order will be blowing air directly onto the ram to aid in cooling.
Also had to remove one of the two Steel support bars from the case. Silverstone thought it was a good idea to place one of them directly across the path of the CPU HSF. This was fine for the stock fan on the Scythe Big Shuriken, but that fan sucked big-time, temps while folding at 3GHz were a whopping 75C with the stock 10mm thick fan. In order to mount a 25mm fan, I had to remove the support bar. It's not going to be going back & forth between LAN parties, so it should be fine without it, but an extra 1/4 in case height would have fixed that problem...
So on to the pr0n:
Case opened & running:

Very tight fit... No room or space for any decent cable management

Really need to have a customized PSU with shortened cables. Fortunately, I have the NeoHE with modularized cables, but it still has a lot of extra length in the cables that are there. Unfortunately, with no top/bottom fan on the NeoHE, hiding the cables under the Optical drive causes the PSU to get VERY hot as they block the airflow through the PSU. so I had to stuff them beside the CPU HSF.
Could also use two 6 inch and one 8 inch SATA cables to help cut down the clutter.
And did I mention it was a tight fit....

If either the PSU or Optical drive were just 1mm longer, it wouldn't have fit. As is, the SATA power & data cables on the optical drive are pressed into the back of the PSU, and I had to force the optical drive in by about 1/2mm to get the mounting screws in place.
It's nice that the case has a top air vent, but IMO, it could stand to be about 30% larger.

Here it is all closed up & 'ready for delivery'

I'll replace the Plextor with my current LG Blu-Ray burner next pay-day when I upgrade my PC with LG's new 14X Blu-Ray burner. The Plextor's more or less just a place holder right now. Although it's a "burner", it can only read CD's & DVD's, & only does that some of the time. Had to Install Windows from USB Compact Flash disk.
Final thought.... The case looks great, but IMO, it's a nightmare to work with. Everything is so cramped, and needlessly so. Case dimensions: 4.13"H x 17.32" W x 13.39" D Compare that to say a Harmon Kardon AVR3650 A/V Receiver at 6.5" H x 17.32" W x 17.125" D, and you can easily see that SilverStone could easily add more space to this case & it would still be right at home in any home entertainment center.
SilverStone also could have alleviated some of the hastle with a properly designed drive carrier. By recessing the 2.5" mount by 1/2 inch into the plastic carrier, my 3.5" full sized hard drive could have been mounted on top of the drive carrier. This would have freed up the space underneath the optical drive to tuck away the excess cable lengths and made for a much nicer looking build. But with the way it's currently designed, I would have to use custom made spacers to mounta 3.5" HDD above the 2.5" SSD, & then I wouldn't be able to put the cover on cause the HDD would stick up to high
