If i were building a computer around the 7980SE cpu, below is what i'd pick. FYI, you can go to https://uk.pcpartpicker.com/list/ and insert or select your own components, and parts picker will automatically flag you when components you've selected are incompatible
CPU Intel - Core i9-7980XE 2.6GHz 18-Core Processor £1735.90
CPU Cooler - Noctua - NH-D15 82.5 CFM CPU Cooler £77.99
Motherboard - ASRock - X299 Taichi ATX LGA2066 Motherboard £281.76

Samsung - 960 PRO 512GB M.2-2280 Solid State Drive £269.99
Samsung - 960 PRO 512GB M.2-2280 Solid State Drive £269.99

Total: £4904.92
That price also includes a 4k 27" monitor (400 uk pounds)- if you're going to be editing 4k video, you need a 4k monitor. If you're only going to be editing drone footage, you can get away with a $100 1920x1080 monitor
- it also includes a 4k capable blu-ray player
Memory - i went with DDR-2666 as that CPU, as most of the X series, only supports 2666 - anything faster would be a waste - i learned that mistake on my 5960x cpu.
I went with an air cooler as if you google for and review any of the cooler comparisons, you'll find there's never more than 1 or 2 degrees C between the Noctura DH-15 and the watercoolers - considering the complication of water cooling, the noise of the water pump, and the risk of leakage (while small), risk of pump breaking down, and they do, i just don't see the return for all that. Air cooler is much simpler and reliable
The case has two external 5.25" bays - one for the blu-ray drive, and the 2nd, i like to use for one of the two bay hot swap trays https://www.amazon.com/Kingwin-2-5-Inch-Internal-Tray-Less-KF-251-BK/dp/B00475DQ6Y/ref=sr_1_1?s=electronics&ie=UTF8&qid=1514317097&sr=1-1&keywords=kingwin+Dual+Bay+2.5+tray. That AeroCool case also has really good airflow and is very quiet plus it has a number of internal HDD bays for expansion
I connect one tray to a sata port, and the 2nd one i only connect a power cable to it. Reason is, Sata SSDs require power to keep from corrupting data on them, but i like to do a complete clone of my OS drive once i've set it up, cloning it to a samsung sata SSD and as it's connected to a Sata port (not thru USB) it clones in 20-25 minutes) then I move it to the 2nd tray without a sata connection - that way i know a virus or malware can't infect it. But the purpose is, when i am hit with a virus, rather than go thru the 6-8 hour ritual to totally eradicate that virus, i can simply clone the backup drive back to the OS drive and be back in business in short order.
If you go this route, just remember to first boot up on the backup drive, then do a "wipe" on your OS drive, in fact wipe it 3X, then clone the backup back to the OS drive
hope that helps
if you do build that rig or any other, once you've got the parts, read the motherboard installation manual twice (i'm assuming this will be your first build) - read all instructions carefully and take your time. The first you build, and hit the power button to fire it up for the first time, you'll almost feel like a new father.
If you have any questions during the build be sure to post here - there'll be a lot of folks that'll be glad to help
fwiw
PS - if you want to reduce the cost, i'd change the following items
Samsung 960 PRO 512 GB to 960 Evo 500 GB, savings of 54 uk pounds each, x2 = 108 uk pounds
MSI GTX 1080 Ti 11 GB to MSI GTX 1070 Ti 8G 8 GB savings = 265 uk pounds
