Hello, This is one of my first posts on here! anyhoo, i was just wondering if someone experienced could help out! I have a massive chieftec case - the fulltower version, which i brought with the idea of someday fitting watercooling in it. I have an old system (xp mobile 2500+ - does 2400 on air/slk900a-no mounting holes on gigabyte 7nnxp/1gb ram/raid0seagate 160gbX2/radeon9800pro/sbaudigy2zs) and was wondering on the following: 1) is it worth my while to go water cooled? 2) how would i go about cutting the case - buy a jigsaw, or buy holesaw? 3) i thought a complete upgrade (ath64 3200/dfi nf4/1gb tccd/7800gtx pcie) isnt worth doing really unless i go the whole hog (like ive mentioned) - or would it be worth moving 'up' (if thats the right word) to p4 2.8c/875p mobo/1gbtccd - keep gfx? 4) i know of coolercases.co.uk being the only place to get stuff from - anyone else worth looking at before plumping? i get my student loan soon and need to decide between these options: 1) water cooled - keep this system 2) go the whole hog ath64-route 3) water cooled - p4 route 4) keep my money and save it for my elective travel later in the year? any advice would me much appreciated, but ive never done water cooling before, but assume i need the SHD dd kits - but rbx or tdx, and is there more than one type of SHD - ie one for rbx one for tdx?) well, i look forward to any reply! thanks!
