upgrade H2O setup

[banger9365]

I am looking to upgrade my water cooling ,
I've got this http://www.overclockers.co.uk/showproduct.php?prodid=WC-011-XS&groupid=962&catid=2141&subcat= its two year old now
replacing it with http://www.overclockers.co.uk/showproduct.php?prodid=WC-140-XS&groupid=962&catid=2141&subcat= coming today

got an old ThermoChill PA120.2 (before they changed the screw holes)and a SRI 120.2 rad ,one off the first ones they made ,yes they are old very old ,
which i do not want to really change ,they work fine ,or would a modern 120.3 be better ?,
case is a haf 932 one off the first ones

tubes need to change them any ideas ,and i would like compression fitting too?
cpu block an EK supreme LT block ,which is a few years old too,are they still good or is it old hag like the rest ,
its been running for about 2.5 years plus know with the water changed every 12 month or so ,with a silver coil
Fans are 1850 rpm gentle typhoons

any ideas has i look at the new stuff and i have not got a clue apart from the pumps ,i know the D5 is still good

i've got about £100 left for tubes and fitting and can go more if its worth it

thanks .i think i will stick with water and a kill coil,that i do know works well,
instead off clear tubes i will go coloured and 4 off each compression fitting to try
thanks for you help lads(your making an old man think now thanks)
