hmm, theres alot of blocks / rads / pumps, but i personaly like apooge GTZ or GT if you dont have money. from swiftech. also PA120.1 (or .2 / .3 if you got space lol) are great, a good pump is the laing (aka swiftech MCP665) but theres alot of watercooling itens, so all i can do is give some tips, like:
- never get a WC kit (or at least 90% of them lol),that's because almost all of them sux and arent cheap, the swiftech one isnt a bad one (and probably one of the small group that actualy works)
- you can make your own coolant (destiled water / some biocide (pt_nuke) / some uv dyes), or you can buy, that dont makes diff anyways but you will pay more if you buy they already made.
- never, remember, never, put coper and aluminum together, it will make somethign called galvanic corrosion and that isnt good for you loop. (if you put coper / and aluminum on the loop your coolant (the one self made) will need some anti-corrosion aditives)
also try looking for guides, really they explain alot better than me
a good one is
