I searched and compared prices on Newegg and Tigerdirect to get the better deals, and here is what I came up with for the needed parts for the project:

• Motherboard - MSI 970A-G43 (for the new system)
• Memory - G.SKILL Ripjaws X Series 16GB 1333 DDR3 (for the main system, and 8GB from it will be used in the new system)
• CPU Cooler - Cooler Master Hyper 212 EVO (for the new system)
• Processor - AMD FX-8370E (for main system and the FX-8120 will go in the new system)
• Power Supply - Corsair RM750 Modular Power Supply (for the main system and the Ultra 700 will go into the new system)
• Case Fans - 2 Corsair AF140 Quiet Edition 140mm (for the new case)

This still leaves me wanting four large drives to build the RAID 5 array, but the budget won't cover them, so they will have to wait, maybe till next year's tax refund.  For now, it looks like I will be simply implementing a RAID 1 with 2TB drives, just like what is currently in the Dell.

Since a few parts for the new system will be coming from my primary system, I have to perform the upgrades to my primary system before I can start building the new one.  Once I upgrade the memory from its current 16GB to 24GB, upgrade the processor from the FX-8120 to the FX-8370E, and swap the Ultra 700W to the Corsair RM750; then I'll be ready to build the new computer.

The upgrades to the HTPC can go last as it will just be inheriting parts from the Dell that are not needed for the new system.

Also, before I power down the Dell for the last time, I have to complete a full backup of the RAID array to an external drive as well as backing up the primary hard drive.  While there may be a slight chance of moving the RAID array to the new system without having to rebuild it, I need to be prepared.  Besides, if never hurts to back up hard drives.

So here is the plan:

Project 2015 - Phase 1 - Upgrading Primary System:

1. Restart the primary computer to enter the BIOS
2. Reset the BIOS to factory defaults, just to make sure it will be prepared for the new processor
3. Shut down primary system
4. Remove existing power supply, 2 4GB DDR3 modules, CPU heatsink, and CPU.
5. Install the new FX-8370E processor
6. Re-install the CPU cooler
7. Install the new 2 8GB DDR3 modules
8. Install the new RM750 power supply
9. Boot up and test the upgraded system to make sure everything is working properly.  If everything looks good, move onto Phase 2.  If not, troubleshooting time.

Project 2015 - Phase 2 - New File Server Construction:

1. Complete full backup of primary drive and RAID array on the Dell to an external drive
2. Once backup is completed, power down Dell
3. Remove drives, video card, card reader and CPU from Dell
4. Install the new motherboard in the new case
5. Install the additional case fans
6. Install the repurposed power supply
7. Install the repurposed CPU
8. Install the repurposed RAM
9. Install the repurposed drives
10. Install new CPU cooler
11. Install the repurposed video card
12. Power up and test
13. Configure RAID array
14. Reboot and test
15. If everything looks good, move onto Phase 3.  If not, troubleshooting time.

Project 2015 - Phase 3 - HTPC Upgrades:

1. Restart HTPC and reset BIOS to factory defaults
2. Shut down HTPC
3. Remove CPU and card reader from the Dell
4. Remove CPU cooler and CPU
5. Install repurposed CPU from the Dell
6. Reinstall CPU cooler
7. Install card reader
8. Power up and test
9. Install drivers for reader and test

Once all phases are complete, I will have upgraded two systems and built a third which replaces the oldest system on my home network.
