You can't cheap much on the watercooling. Build a nice air system and add water later.
Your WC list is full of bad mis-informed wrong stuff. You list a pump for $39. Don't think so.
You have listed the expensive not needed liquid to cool.
Wayy outdated CPU block.
You list a TT cooler for the GPU.
"Friends don't let friends buy Thermaltake." Watercooling for a GPU is always close to $100, and up. You need to cool the VRAM AND THE VREAGS if using a GPU only block. A accepted GPU only block is $60 or so.
The rad you list is VERY old, need high FPI fans, inefficient and rarely bought by a knowedgeble waterooler. Not a pro, a normal new guy.
Your about 3 weeks short in the research department to order ANY watercooling parts. More or less.
EDIT: I looked up your internet click n buy on the GPU block. I need to say, if you picked that block for GPU cooling you are not ready, 100% to even order ONE single WC part.
OMG. That is from 2005 or before, the top is cheap plastic, the fittings suck, and probably steel, not coated brass, not barely able to even cool a modern GPU. You can point and click all you want, but untill you spend a week++ in our stickies and readin many posts, your not ready. I never pull punches here, I tell you how it is. You do what you want. Peeps we help here build geat hassle free WC rigs usually. So I'm saying what you must hear, not what you want to hear.
Your looking at $400-$600 for a quality WC loop, one that will last forever for your CPU and GPU.
Our stickies and this link here will get you started.

An auto is NOT a watercooled PC, believe me. It's similar, but wayy different.
