That is the best way to go if you can maintain it yourself. Your friend may be helpful but it is hard to be certain that a friend will always be there when you need some help forums are great for advice but it can be very frustrating trying to solve anything but the simplest problem via forum.
So if you go with a desktop and your focus is on editing you will probably be best served by focusing on the the specific components that matter. Of course you need to see what the minimum HW configuration recommended by your software is keeping in mind that the performance at the minimum config will be less than you might like. Given that you only upgrade every 4-5 years you really well be best served using the latest components and reserving some performance headroom for future applications. Also do you have a budget? That will determine a lot.
Specific things to look at:
1. Processor & motherboard - go with latest intel i7 and a mainstream (not a gaming) motherboard. There is a lot of range in price/perf here.
2. Display - 4K displays are pricey but mandatory in your case. This is the part you look at everyday so don't shortchange yourself. Number one budget buster here.
3. Storage - a 512 GB SSD will serve you well as system drive (great performance for the system and editing) but you need storage for all the huge video files you will be working with. Go with a good 4 or TB 7200 RPM HDD in addition to the SSD. Storage is the number two budget buster.
4. Graphics - get yourself a good GPU but unless you really want to game or do multiple (more than 2) displays something in the range of a GeForce 1060 should be great.
5. RAM - 16 GB will take care of you nicely - the motherboard usually has four slots and memory goes in pairs. So install a 2x8 memory pair and that will leave room to add another pair and double to 32 GB if you desire. Also buy the fasted clock memory that is listed on the motherboard vendors compatibility list.
OK, he's been ill but come back to me with these specs, which are as always for me, might as well be written in Clingon - price wise they're pretty similar so I'm just wondering if this will more than do - I plan to edit largely 4k, and I'm inclined towards an ultra wide monitor like this;
