Few months ago I went with my own server with 2 x e5
Now you can build fantastic workstation and for less money since AMD released 8 core Ryzen for 2-3-4 times less money than Intel
Also you dont need EEC ram as in real world the normal ram won't give any errors (not that you will host sites on the PC but)
Go ddr4 3000+ MHz - its fast and its up to date with the new motherboards
Now I dont know if You have bought any parts yet (sorry didnt read the whole thing, but saw u have bost 40 mins ago) but here are my 2 cents
1st and most important - get great PSU - good energy for all your parts.
2nd - get 32gb+ ram as I found 16gb isnt doing good job for a lot of tasks
3rd - Getting the new Ryzen is a no brainer for these money
4th - Get a Wi-fi Adapter - If my Lan Fails it automatically gets my 4g as a backup (havent test it with real life internet drop but I plugged out the cable and it took the wifie in 2 sec). Now, my lan hasn't failed yet but for 20$ its good + to asure good uptime for my sites.
5th - Get a GPU - few weeks I was with my MB GPU but getting GTX 1050ti was good option since I am doing few photoshop projects and after effects projects too... + I get it for 109$ - again no brainer for 4gb card.
6th - Get DUST PROOF case with GOOD AIR FLOW - very important. My advice is to get Thermaltake cases as most of them have magnetic dustproof filters on every side.
7th - Get M2 - its faster than normal SSD and there wont be more cables and get another storage for backup + dont forget to use cloud as backup
And finally I will put here the build:

P.S You can change to micro MB and get the Thermaltake v21 - it is more compact (I find v71 very big case for a workstation but it does the job great). If you also want to use this build for gaming all you have to do is to change the GPU (for 1080ti for example) and you still won't hit 3000$
