Bought a preinstalled WC case (need advice)

[d19z]

Hello

After much thought and consideration I bought this ;

Computer hardware and software at amazing prices, available online from Scan Computers UK

The description states;

Case: Coolermaster Mystique RC-631-KWN1 - Black Alu Window with preinstalled water-cooling
CPU cooler: NexXxos XP Light (incl. all mounting plates for für AMD XP, AMD 64, Socket 754, 939, 940, Intel Socket 775)
Pump: Eheim 600 Station II 12V
Radiator: Black-ICE Pro III
Fan: 2x Alphacool 120 19dBa fan
Tubing: 10mm
Connections: Fittings 10/8mm

but this is still very vague, it only has on loop, I plan to add another for my gfx card, but I don't understand, surly this system must have a resivior, or does the pump act as one?

I plan to change the cpu block to something beefier, with more surface area, but only just realised the tubing size is tiny, so now I'm limited.

I've got a e6600 B2 @ 1.4-1.5V I'm just wondering roughly what sort of cooling performance I can get out of this? and what sort of modifications I can do to improve the cooling?

thx in advance

Can you take a picture of the case internals?
