It'll be fine, leave it leak testing at least overnight.

I stuck mine in a washing up bowl with loads of kitchen roll underneath, if you're careful it shouldn't leak when you fit it, but you could always bang some kitchen roll over the top of your video card (just until you're sure it's not leaking) just in case it does end up dripping.
 
idealy fit it into the case as if it was going to be running, but try and take the motherboard out, its tight but worth it.

obviosly you dont want to have any power going to any on the components when leak testing, therefore use the hotwise method on your PSU ( paperclip in across the green and a black wire)

IF its an impossibility to leak test in the case with the hardware removed, attach everything to the PC except the power to the mainboard and other bits, just the pump. ( use the hotwrie method again)

in the event of a leak. source the leak, fix it and keep testing, if water spills onto a component teake it out, and let it dry offf, because there was no power going to ift it SHIOULD be okay afetr a day or two of drying.

check all barbs / connections on the parts before you think about putting water in them.

and dont be alarmed if the pump doesnt sent water around ! it just means theres air in the pump, andf it cant budge it.just make surte the res is feeing the puump okay.

testing out side of the case defeats the object of leak testing IMHO, andthing can happen to the connections while moving it in and out.
bad idea IMO
 
I dry-fitted all my components into the case with mobo installed, I then removed the WC system and "trigged" it all up on boxes and tape etc to more-or-less resemble the positions the components would be in the case (with the rad at the top) including trying to put as much strain on the tubing as would be when fully installed.

I only tested for 5 hours coz Im an impatient git, but I secured all barbs well - Ive done a lot of plumbing in houses before, so I was fairly certain it wouldnt leak.

bleeding air out through the rad took an age though, I suspest it might be easier to put the res at the top of the loop and just let the air find it way out with the res cap off.
 
well, im going to go fit it in my case, just gonna have to have a lot of tissue handy... would you tighten the nutts up by hand or go as tight as you can get with pliars?
 
by hand !!!!!!!
dont use tools ! lol
too tight is odten as bad as too loose, specialy with the type of fittings you have.

if you have work to do on ** PC mate, leave it til tomorrow. honestluy its best to take your time otherwise you could have a VERY expensive problem

thats the problem though... i always have work to do on it, and if im not doing anything then its buisy doing something for me lol, its on 24/7 365 days a year.
 
when tightening the barb threads (WITH PTFE APPLIED) into block etc I just did them up by hand and then gave then a slight tweak with a pair of grips just to make sure they had bitten in well - as said dont go too far - especially with plexi tops!
 
leak test as long as you possibly can.... many a component has gone swimming due to this little oversight.

I swear by PTFE and silicon sealant. keep some handy, and some tissue paper for emergencies ( not that kind! :P I know what you're thinking... dirty little ***** :p)
