I wanted to:
-- Install an mSSD
-- Have the mSSD be my OS drive
-- Make a fresh installation of Windows
To start, I was unable to make a truely virgin installation of Windows. I tried installing via USB, via Windows 8.0 DVD, via Windows 8.1 DVD, using both home and Pro license versions and I could find NO way to install virgin Windows (without the Acer bloatware). The best option I could find is to make an external recovery, allow it to install to a formatted hard drive, then you have a bloat-ware laiden but otherwise untouched Windows install. Here are before/after pics of my installation immediately after recovery (with bloatware), then after I manually uninstalled bloatware:


Acer Recovery Discs can be created by using the Acer eRecovery Management program. An external USB CD or DVD writer is required in order to create the Recovery CDs or DVDs.
- Plug in your AC adapter.
- Click Start, and then All programs.
- Click Acer and then Acer eRecovery Management.
- You may be prompted to enter or create a password. Once created, this password will be required to use Acer eRecovery Management in the future.
- In the next window, select Backup.
- Insert a blank CD or DVD into the external CD or DVD writer.
- Click on Create Factory Default Disc and then click Start.
With that external recovery, you can now:
-- Remove back cover of device
-- Install mSSD
-- Reinstall back cover of device
-- Plug in your external HDD or DVD that has the recovery on it
-- Boot the PC
-- Immediately press Alt+F10 to access the recovery options
-- Make sure you select the correct hard drive
-- After installing, you can format the included 1TB HDD if you please. Then, you will have a fresh, empty 1TB HDD and an mSATA SSD of your choosing running the OS at super speed
Here is the torx bit set I used. Tamper-proof is not necessary, I selected that for other reasons. I think it is a T8 bit that I used (per the description on the bit, shown in below picture album).

Here are the posts that gave me enough information to do what I've shown above (thanks to the posters!):
