I really hope to get one of these, it's not that I don't have GPUs already but that I need something a little stonger than what I have on hand. Yes I'm a gamer and NOT by any stretch am I a miner or a scalper, but I'm also literally and doctor verifiably 75% blind. Because of this I don't game much especially shooters, what i really need it for is my software used to see my computer screen which is extremely GPU and Memory intensive. I'd trade 3 lower cards just to get a 30 or 6000 series card. 

I'm not sure of the connection hub on the ML fans but the LL fan hub does not connect to the RGB header at all you will use the USB 2.0 Header instead. So this will leave your RGB headers free to use with other AURA Sync compatible fans. I'm not sure of the hardware you plan to use but remember also that fans will draw power from the PSU and if you plan to use an AIO,  you may want to up the PSU to at least 600w just to be safe. Most systems I build I don't go below 650w just for the sake of head room for smaller builds. 

Yes, if you go with the TT controller you must also go with TT devices only.
Yes, the strips come with extenders and each strip is about 12-14 inches I'm guessing. https://www.ttpremium.com/product/pacific-lumi-plus-led-strip-3-pack/
You might find someone selling bundles like that but it's not likely unless it's like ebay or something.
To answer the configuration question. If you wanted say 3x fans and 6x strips that's 9 pieces so all would fit on a single controller and the controller would use one SATA power to the PSU and then plug directly into the ARGB 3-PIN on the motherboard and that's it. You would use the ASUS AURA or whatever RGB handler software your motherboard uses to control the RGB affects. Here's another picture to show the different lighting for each component I have which are all controlled by AURA. Please excuse the messy cable management. 

As previously stated I have 12x fans and 6x strips, so I'm actually using 1 of the 9 port controllers and 1 of the 5 port USB controllers that is TT software driven.

Also just to show you the LED strips alone give off a good amount of light on their own, not sure how much RGB is too much for your liking. 

The best solution I have is thermaltake they have a 9 port ARGB controller you can get on Amazon for around $30. The fans can be a bit more expensive but as long as you don't go with the Trio version fans you can put up to 9 fans or a mix of fans and strips on the one controller. Then just add cheap LED strips to the standard RGB 4-pin headers if you wish. It is compatible with the ASUS AURA as well. Or if you want to go with Thermaltake's software instead you can buy the fans and strips only and use the included 9-Pin USB controller that will support up to 5 fans/strips at once, note you can chain the controllers as well so you don't use up both of you USB headers on the board. I had option 2 on my old asus x470 board and now use option 1 on my asus x570. Just a side note, with Thermaltake you cannot mix and match with other brands, their fans and strips use a 9-pin connector (not to be confused with a USB header but looks the exact same) that plugs into their own controllers. I know there are others on the market like cooler master that you can mix and match with other products. I just wanted to be clear on this so if you chose my route you don't buy the 9 port controller and expect to buy cheaper fans to use with it. Others may have differed  opinions on better fans and the like as well but I can say I've not had any problems at all with mine even in smaller cases and heavy use cpu loads they will keep thing nice and cool provided the placement configuration is right just like with any other fans.

Sorry i don't have anything on the Fractal Case or GPU situation. I'm using the Thermaltake View 71 and an RX 5700 XT. 
I have a total of 12 fans and 6 LED strips. 

That's workable. I thought about it just didnt have the extra $50 at that moment.

This is a good GPU too especially for 100$
 
 
Go for the non-X version though  
 
 
So, what I understood, you want to upgrade your computer then give to your friend to buy new stuff for you, is that correct ? 
 
In that case you should go for the 1st build i made with the rx570 :

After that you could upgrade the GPU, motherboard and CPU to your own need and.
 
If your friend doesn't need a beefy computer you could go for the high end one i made and build him something around the rx570 GPU.
 

Hello,
 
You didn't specify a country so it's in USD $ :

This is neither low or high end but it's a pretty solid build.
