Cool GTX
So, you'll mod my full set of PSU cables for my 1600 PSU for $40 ?

HA!!! no... i now have full respect for whomever does this by hand. though a lot of these cable moders have set lengths for a reason, automation. still though this is an art form.

OMG, i thought 2 hours for 1 was bad. once i took out my volt meter it only got worse... i found out that i had bad connections that i had to redo! 6 hours later i got 2 finished and operational... but ya totally worth it when you look at the before and after.
 

They are looking sharp
 
Hope your finger tips are not all numb and bloody
 
A great crimping tool is worth its weight in gold
 
Using a hand operated auto -stripper to get consistent cuts ?

no, an auto stripper would be nice if i wasn't sleeving them but what i am doing i can strip a good inch and let the sleeve cover the wire, not that i am doing this. so i do not have to worry about getting exactly 2-3mm of wire stripped every time. the thing that is taking forever is getting the 2 wires and sleeving into a single crimp. getting that right takes a lot of time and patients...measuring and making the other single end takes about half as long per crimp. but also ya, my finger tips are rather sore and i did cut myself but it didn't bleed.

Man, that cable mod seems to require more patience than I can muster. I just wish PSU came with more 8pin cables, not these stupid 6+2 combos. Sadly, they don't make them for my psu or I'd buy straight 8pin pcie cables.

welp, i just ordered the last of my parts and i compiled a list of all the parts that went into this build, so far and does not include modified parts like the cables mentioned above. i went ahead and edited the main post with it but for those interested i'll also list here, wish there was a [hide] or [spoiler] tag i could wrap it in... also as i said before the liquid cooling parts will not arrive until the 22nd, if they don't get held in customs for any reason, and at that point till the 25th i will be working to complete this build to its 100% finished state, if all goes well.

i just got shipping confirmation that all the EK parts will arrive in two days. i have a family reunion this Saturday so i will not be able to do much of anything then but i do hope to get a solid start on it asap and get it wrapped up by the 19th if at all possible. i am soo excited!

Man that's quite a project! I have a couple thoughts for you: good luck putting the water blocks on all those 1070s. Getting the old coolers off, cleaning up the die, then putting it back together with the water block on takes a while, and you're doing it five times! 
 
Secondly, have you thought about just waiting for EVGA to finally ship those power adaptors that will go down the end of the card and let your power cables plug in down at the bottom of the card? That would clean up the look tremendously.

Looking forward to seeing those blocks
 
How thick are those XSPC 420mm radiators; seems a little small for 5 GPU + CPU ?
 
What pump(s) are you planning on ?
 
What fans are you using ?

Check out his extensive list CoolGTX, He is using the new Corsair Maglev fans.  The rad's are 140MM .":Best cooling capacity in the 45mm thick radiator class" X2 << [using 2 of them]

I was just looking at some of his items, and was thinking.. " man that's cool that he knows what he wants in his layout."
Interesting the 1080 blocks are same for 1070. Quite a project Chris, enjoy the build. I love it so far!! I would enjoy the heck out of that. Also noticed he is using the hardline and also some soft tube.
 
Edit: I did have a question on the temp sensor. Do you already have something that reads the signal for that? I have no doubt ,you know wth you're doing ,just curious. 
"Bare coolant sensor compatible with Koolance multi-sensor systems. Designed to fit any G 1/4 BSPP (parallel) thread fitting socket. Wire length = 30" (76cm). NOTE: This sensor will only work with Koolance products which use 10K Ohm @25°C sensors (first introduced in 2011)."
