The standard is the Liang DDC, or many other brands that are just rebadged Liang DDC pumps. The D5 is another great Liang pump that is popular. The DDC seems to be more popular now. Look into both and read up on the differences...it's a toss up.
You can buy a tower reservoir with the DDC pump attached. It's an easy install. I'd consider a single 360mm+ radiator. You go over 500mm actually. It'll handle a CPU and video cards no problem. No need for dual radiators. Fans can go on either side of the radiator without any performance difference and push pull isn't necessary.
A good case is the Fractal Define S. Same as the R5 but without the drive cages so it's cheaper, yet the exact same quality. It has room for 2 drives on the back side. Most people use a single SSD and storage drive anyways. It has no 5 1/4" cage for cd-roms though, but many people now get an external drive and plug it in once a year to install windows and motherboard drivers. Having all the cages removed makes tons of space for the watercooling.
At $80 it's an amazing watercooling deal of a case. Why pay $150 for a case to remove the cages and throw them aside to make room for the watercooling. Fractal did that for you and only charges $80 for a $140 case. It's nice and wide open inside, with a nice large window.
If you want a really super nice case, the large Corsair Obsidian cases are nice. Also Corsair makes a reverse case with the window on the right so you see the video card heatsink facing up instead of down. It's cool. Also the R5 version of the Fractal S if you need the CD-ROM drive bay.
Also consider just getting a complete watercooling kit in a box. EKWB has one. It'll have all the components you need. You should only need 3 tubes:
1 - Rad to Reservoir
2 - Reservoir to waterblock
3 - waterblock to radiator
I don't know where you get 10 tubes. Unless you have a seperate pump, a seperate reservoir or 5 1/4" reservoir bay, and a video card block, motherboard, and memory cooling.
I like the integrated DDC/tower reservoir pumps. You can also get an integrated D5 pump in a 5 1/4" bay reservoir.
Check out EKWB for all the components.
