Water Cooling an Antec 300 – Q9550 2

So, I have decided to water cool my Antec 300 case….which acts as my 24/7 HTPC workhorse.

Specs :

Antec 300
2GBx4 DDR2
3 x 2TB Samsung HDD
2 x 2TB WD Drives (backups)
Asus P5N-D

I started with an RS240 XSPC kit, but found the pump to be far too loud and not adequate for my set up, so I am moving to the following build :

Water Cooling specs :

Reservoir : RS240 pump/res comboKoolance RP-402X2 Dual 5.25 Reservoir for 1-2 DDC Pumps + Swiftech MCP 350’s
Radiator : RS240 from the RS240 Kit/Combo
Tubing : rimoFlex Pro LRT UV Red Tubing – 1/2in. ID X 3/4in. OD
Barbs : What came with the kit
Fans : 4 x SCythe SFF21G
90 Degree Fitting : 4 x Koolance G1/4 Swivel 90° Angled Barb
45 Degree Fitting : 2 x Koolance Swiveling G1/4 Threaded 45 Degree Low Profile Angle Fitting
CPU Block : Came with the kit – XSPC CPU block
Northbridge block : Custom fabbed block from a guy on overclock.net
PCI Tube G1/4 Slot : Koolance L-Bracket with Dual G 1/4 Socket Fittings (BKT-PCI-G)
Radblock Mount : Swiftech MCB-120™ “Radbox”

I have changed a few things from when I started,so I will post new pictures once completed again. The pumps will run serial, with that little koolance res kit.

    Only one pump in this setup, located in the res as well, up front in the 1×5.25″ din! You can actually add a second pump to this setup if needed.
