Thanks for the advice about the plexi guys. I've been having terrible trouble with my rad today. In trying to fix the leak, I've actually made it worse. I'm trying a new tactic now but it's going to take a while to dry. The watercooling system is now going completely internal as was originally planned. So far I've fitted the exhaust fan for my rad with rubber gromets and a spiral grill. The rad itself is going to go in the 3.5" bay, above my floppy mod (read up). I've also fitted a new reservoir from wizarddesigns.co.uk (great service btw). This was just the simple task of widening the top blowhole and removing the grate. Please note, watercooling a Coolermaster case and using an AquaTube res is "Icecube"'s idea and I have totally ripped off his idea. Any credit/kudos/whatever for the idea should go to him. Pic so far.. Rad permitting, I should be finishing the watercooling setup tomorrow, and also doing the window.
