Well I have finally completed my first water-cooled computer and thought I'd share it here.
The rig is as follows:
ABIT NF7-S (rev.2)
AMD Athlon XP 2800+ (not over-clocked yet but I'm about to start)
ATI Radeon 9700 Pro
Corsair XMS TwinX 1Gb @ 3700
2 x Maxtor 80Gb SATA @ 7200rpm - RAID 1
Antec TrueBlue 480W PSU
Matrix Orbital LCD
CoolerMaster ATC-201
Water cooling consists of the following:
Danger Den Maze 4 (CPU & GPU)
Danger Den Z-Chipset (NB)
Danger Den tubing (1/2")
Eheim 1250 pump
Aqua Computers AquaTube res
Thermochill HE 120.1 rad
Criticool Powerplant pump relay
Here's a picture of the whole setup:
The CPU block:
The GPU block:
The pump is mounted in the bottom of the 3.5" drive cage with an anti-vibration mounting kit:
The radiator and reservoir are at the top of the case, naturally:
I used 1/2" tubing and fittings throughout:
