Thats an american competitor....
Aside from that it looks good, remarkably for a first spec. There's a couple of parts you don't need, the chipset rubber pads and the feser one being the main ones. Distilled water @ 60p a litre is a better idea than feser if you don't care deeply about it being red.
Hose clamps look like they might be jubilee clamps. If they are, fine, otherwise buy jubilee clamps from a hardware store. Shrouds are worth considering if you have space, hollowed out fans are the way to go if you don't want to buy shrouds.
Putting the board and cpu under at once is pretty brave, it's probably worth setting it up with just the cpu block first, then adding the chipset in once that's working well. You've specified that really well.
edit: 1m of tygon is almost certainly too little
