Well I can't seem to find the pics I was on about, but I have updated the Imgur; please feel free:

As for the mess-ups I mentioned (I used the c-word for willy previously and it got starred out; it's not an expletive used in this context is it?):
What happened was, first, I broke the strap/bracket thing holding the pump/res combo; it was really to easy to break so beware if you're going with this kit: I took it off to re-position the res so you could see the "EK" logo-thing when looking down into the case via the window (which I don't have as I can't find it in stock anywhere, and the few places that do have it in stock cancel my order as they DON'T ACTUALLY HAVE IT). Annoying as hell as I have to wait for that money to go back into my account each time
I bent the strap bit, not very far or with much force at all and *snap* - gutted. Managed to superglue it back together - if you look closely in the pics you'll see the crack.
Also, the extra tubing I ordered was the wrong size. I discovered this maybe 2 hours after breaking the res clip, and raged like a hormonal teen. I'd had enough; I flung the tubing up above my head and slammed it into the ground as hard as I could - as I did this, it created a whip effect with the loose tubing which cracked quite hard (and loud) on my exposed back (I was just about to shower!) and boy did that hurt!
i managed to use the now non-essential tubing to create my filler tube friend thingy, So I won;t be retuning it as I cut it. I'm sure it'll come in handy for something.
Also, After the first test-mount of the rad and the res, I found that I did have enough space for push-pull - only to find after actually successfully mounting both (had trouble with the radiator, ugh!) that this wasn't the case - I hadn't fixed the rad in when I measured on the test fit, turns out I'm about 5mm short for fans on the inside. The additional fans will be coming this week; I might pop one in as I can fr it on the topmost mount, not sure how good (or not) that would look though.
All in all, I learned a few things during this experience; the most important one being that decisions made in haste will come back to bite you in the ass. But then I already knew that.
Also, don't watercool in the Define R4; just buy a new case, it will be much easier in the long run!
Thanks for listening to my rambles!
