Questions about Re-use of Pumps/Rads(3 parts)

[Sephonia]

Question Part 1:

I have a single loop for my CPU set up by my grandfather about 2 years ago. It has not been maintained in any way, I had zero clue there was maintenance to be done on these systems & since I wasn't a part of the build, I didn't learn anything. I do not plan on using the cpu block again, however, I would like to know if it's possible to reuse the Pump/res combo ( http://www.xs-pc.com/discontinued-eol/x2o-750-dual-bayrespump-acrylic-v4 ) or the radiator (30mm x 240mm) for my next build. I'm now wholly aware that I probably have at the very least some corrosion on my CPU block. I saw some dude post about thinking his rad was corroded but turned out to be oxidation instead and he just needed to flush it out. Unfortunately, I have no way of disassembling my rig until 9/28/14(about 2 weeks from now) to physically drain/inspect the loop. Visibly it doesn't seem there is any bacterial/algal growth so maybe I got lucky (Yes, I do have a kill coil in the system.) Additionally, if my fittings aren't corroded, I assume I can re-use those as well?

Question Part 2:

(Prepare for some Advanced stupid here folks) I have a second 30mm x 240mm radiator sitting on the side of my case that has been collecting dust for about a year now. Can I simply flush out the dust and reuse that radiator or did I just throw away money? My main concern is that I won't be able to flush all the dust entirely and I'll end up inevitably gunking up my pump/blocks and causing issues later on.

Question Part 3:
I am attempting to plan a water cooling setup for my next rig (http://pcpartpicker.com/user/Sephonia/saved/gRYRsY). Based on everything I've read so far I should be good to go for the build with the listed components (Obviously, If I can re-use some parts I will be doing that.) 

Proposed Loop:
Swiftech Apogee-XLC  -- CPU Water Block (http://www.swiftech.com/apogeexl.aspx)
EK-FC980 GTX - Acetal  -- GTX 980 Gpu Block(http://www.ekwb.com/shop/ek-fc980-gtx-acetal.html)

EK-RES X3 250 -- 250mm(h), ~440mL Reservoir (http://www.ekwb.com/shop/ek-res-x3-250.html)

EK-D5 Vario X-TOP - Plexi (incl. pump) -- snazzy lookin'  pump that I'm probably overpaying for. (http://www.ekwb.com/shop/ek-d5-vario-x-top-plexi-incl-pump.html)

PrimoChill Tubing 1/2"ID x 3/4"OD

Lots of 1/2"ID x 3/4"OD (G1/4" standard) fittings. Still trying to find some cute ones in pink to match my build, if anyone knows where, please let me know.

Please, for the love of god, do not buy a Maximus board. You will never get your money's worth out of it.

I'd just start completely knew honestly with the pump and res combo. it's just a few extra out of your pocket.

Alright, so new Pump/Res. Any thoughts on current rad's? I'm really hoping the 4 lbs. of dust isn't an issue (exaggerating of course but it's pretty bad...)

wash it out with plain water and viniger, at about 10 to 1 ratio. then flush it out with distilled water. extrenal just vacuum it clean then just wash it off with plain water and a very soft brush like a shaving brush.

@Maxwit44 is that in reference to the dusty one, or both radiators?

 both. Never hurts to flush them out. Couple of years is a long time. And its better to be on the safe side then to watch thing go bad after you've spent all that money.

 

I know Jayztwocents said in one of his videos that He had a loop that He left for 4-5 years? and there wasn't a thing wrong with it.
