Probably the biggest mistake you could make would be buying all the parts from a single mfg. None of them does everything well. EK makes ok (not really good....just ok) blocks, some good rads and some putrid ones, and the rest of their line tends to be subpar. Watercool ha great blocks, reservoirs and pumps....and their rads aren't very good. HWL makes the best rads around, and only makes rads. Phanteks makes nice blocks and fittings, but.....you get the idea. And don't even get me started on Corsair......selling rebranded lowline parts from other mfg at a high price point.
As others have mentioned, Watercool Heatkiller or Aquacomputer for blocks. If that isn't the look you are going for, Phanteks makes excellent quality blocks that always seem to be overlooked in this forum, or XSPC.
HWL rads every time. Just be sure to match the rad with your intended usage - GTS or SR2 for quiet, GTX/GTR for ultimate cooling provided you don't mind deafening fans. And make sure you match appropriate fans to the rads.
Bitspower, Monsoon or even Barrow for fittings. BUT...I would never use anything but a Bitspower or Monsoon rotary fitting.
Monsoon, Heatkiller, Swiftech Maelstrom or XSPC Photon reservoirs.
There is a lot of good stuff out there, it just isn't going to be all from one company.
