New home virtual environment/lab

[Anonimac]

Approximate Purchase Date: this week
Budget Range: not primary concern but tentatively say <5k
System Usage from Most to Least Important: Learning (enterprise IT, security, etc.), home centric stuff (file shares, media storage/encoding, torrent, home automation), site to site VPN to another environment just like mine (virtual domain join), vuln. assessment/penetration testing vm's, etc...
Are you buying a monitor: No
Parts to Upgrade: New build, so everything...mobo, proc., case, ps, nas, etc...
Do you need to buy OS: No (not sure how to answer here...technically yes, since it will be from MSDN/TechNet)
Preferred Website(s) for Parts: No strong preference...slightly favoring Amazon due to Prime membership and easy returns
Location: Houston, Texas
Parts Preferences: Intel
Overclocking: No
SLI or Crossfire: No
Your Monitor Resolution: 1920x1200 but not getting a new monitor and this will be a virtualized Hyper-V or ESXi so likely completely headless
Additional Comments: I am pasting here my thread from a few other places i've asked for advice.

Hi folks, i'm building my first virtual environment and it will be a home build. For breadth and depth in my field i want to emulate a small enterprise so i will be running AD, DC, file shares, SharePoint, mobile device management and enrollement (future), as well as a combination of home centric things like media storage/conversion/cataloging, iTunes, home automation, etc... My personal machines (desktops, laptops, tablets, smartphones) may also be joined to the domain to test mobile device management, certificate enrollement, etc. Other uses also include vulnerability assessment/penetration testing vm's like BackTrack, Samurai, and other custom Linux builds. I also need to be able to do port monitoring and traffic interception on any mobile devices for mobile pen testing.

So having said that...this is what i'm considering buiding:

Processor (x2) Intel CM8062107185405 Xeon E5-2630L 2.0GHz LGA2011
Memory (x2) Kingston 32GB (4 x 8GB) 240-Pin DDR3 SDRAM ECC Registered DDR3 1600 Server Memory DR x4 Model KVR16R11D4K4/32
Hard drive (primary)...may possibly do SSD instead Western Digital VelociRaptor WD4500HLHX 450GB 10000 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
Hard drive (NAS) x 2 Western Digital Caviar Black WD2002FAEX 2TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
Motherboard Asus Z9PE-D16 Dual LGA2011 Xeon/Intel C602-A PCH/4GbE/SSI EEB Server Motherboard (ASMB6-IKVM)
Power Supply SeaSonic X Series X-850 (SS-850KM Active PFC F3) 850W ATX12V v2.3 / EPS 12V v2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply
Case Cooler Master Cosmos II Ultra Tower Computer Case with Aluminum and Steel Body (RC-1200-KKN1)
NAS QNAP TS-869L-US 8Bay Intel D2700 2.13GHz Dual-Core CPU 1GB SATA NAS

I plan to boot/store all my VMs from the NAS so that's why i'm not too concerned about local storage on the server/workstation.
Thoughts? Any major/obvious concerns? Anything obvious i'm missing?
I really appreciate anyone's input and/or suggestions.

And Most Importantly, Why Are You Upgrading: Need to build virtual lab.

Really appreciate any help and expertise this community can provide to gut/insanity check my proposed build.

No thoughts? I'm really trying to make this decision by end of the week so i'd appreciate any input from the community.
