Although I understand water cooling in theory I have no true knowledge of good parts or brands. The plan is to internally mount the radiator by modding my current top panel and copying this; That will then be cooled by my aluminium fan plan for the top panel setup like this; Instead of the filter the radiator will be along the length under the meshx. There will be no fan guards so fingers beware! I may add grills at a later date when I order my planned Q9450 and 55nm gtx260. I have 2 fans spare after I do this so may put them onto the rad underneath but not close enough to block the other 5.25" bays Parts Pump:http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=77_74&products_id=387 cpu block: http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=27_28&products_id=1126 Radiator: http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=37_73&products_id=932 <-- I need it to fit within the top 2 5.25 bays including space for the 25m thickness fans so limitted to 90mm Resevoir:http://www.watercoolinguk.co.uk/catalog/product_info.php?cPath=36&products_id=347 Tubing?? coolant: distilled water with some biocide Fan controller: Scythe Kaze Master Ace 5.25inch Fan Controller - Silver Mainly for other case fans not the watercooling loop Meshx: http://www1.acryan.com/_meshx/meshxpanel.shtml Works out to approx £300 p.s. This won't just be to cool the cpu it will eventually include cooling a 55nm 260, Q9450 and possibly a dedicated 8800gts 640mb as physx. Not worth selling my 8800gts pair second hand money would be to low.
