Unfortunately, removing the sticker to allow the removal of the backplate voids the warranty.... Did alot of digging since this thread, and the GX70 has two 2.5" bays, and three (yes, three) mSATA III ssd mounts configurable in 0, 1, 0+1 raid formation (total speeds up to ~1300mbit/s)
Two ram slots allowing up to 32GB DDR3 1600mhz (2x16) @ 1.35V.
To get to any of those parts, the warranty must be voided. There must be a way to remove that sticker so i can place it back on (to make it look like i didn't void the warranty)
The AMD A-10 5750M Richland APU will support 1866MHZ RAM @ 32GB (16 x2)
I have Ripjaws 1866MHZ ram and its running at full throttle. I haven't tested with the newer 2133 MHZ RAM however, kinda afraid to throw down the money if the CPU or latest BIOS update supports it.
The CPU uses a FS1r2 socket, so any FS1 or FS1r2 chipset will work in it, but the 5750M is the best there is right now. No desktop APU will work in this.
GPU uses a standard M-PCI-E slot, but I haven't used anything other than the 8970 thats in it because there is no real reason to upgrade it at this time.
There are indeed 2x SATA III HDD slots, which the bottom-most one can support thicker Enterprise (2TB+) 2.5" drives. I personally use dual SSD at RAID 0.
The optical drive is upgradeable, but due to the unique shape of the laptop, I do not think you can find anything better than the blu-ray player thats in it, unless you find the GE or GS series laptops with a blu-ray burner.
Keyboard is easily replaced incase you break keys. So is the screen and anything else.
The wireless card I cannot reach, but its pretty high end for this model. The rest of the stuff (Sound, motherboard, etc) is all integrated.
CPU fan is a centrifugal blower design that intakes through the vent in the bottom center, pulls along the GPU, goes into the fan and selectively chooses which sinks to exhaust to. So if on APU, you'll notice more air flow out the side, but when gaming, more airflow out the back. Could watercool the CPU but the GPU is spread out too much.
All in all, I do hope AMD keeps with the FS1r2 slot for the next generation of APU's because the APU in the GX-60/70 is the bottleneck of the system, and Enduro still needs work.
The next generation (GX-70 Destroyer) is EXACTLY the same as the GX-70 that was released before it, just the R9 mobile graphics is a re-branded 8970, and it comes with 12gb 1600mhz RAM (8g+4g)
I HIGHLY recommend dumping Windows 8 for Windows 7, the CPU gets bottlenecked even more due to the heavy CPU usage of Windows 8/8.1. Benchmarks in Windows 7 exceeds the benchmarks set by MSI using Windows 8 in every catagory.
