Ok, I pulled the condenser (full aluminum), it's looks to be in decent condition but definitely needs some cleaning.
I also found this, perfect size for a quad 120mm wc rad, has the fittings and everything (520 x 120 x 35mm{13 FPI}). Unfortunately it's completely made of aluminum, on the plus side: it's really light because of that.
And I found an old water cooler, I'm going to use the compressor from it, would it be good enough? The tank/compressor is roughly 6 x 6 x 6in (or smaller) so i'm thinking it's too small.
