First time using watercooling question

[gus6464]

I recently ordered 2 Opteron 165's for my new gaming rig and Linux box and decided to go water cooling for the two setups but I was wondering if I can use one kit for the 2 pcs. I dont mind also building my own water setup instead of a kit to be able to achieve this. Can one radiator and water pump if I am trying to cool 2 cpus inside 2 different cases? Also if it was possible to do would I also be able to add my new 7800gt to the water setup? I know this question is very noobish but this is first time trying to do my own custom setup so please bare with me. Thanks

I see no problem in you doing that. As long as the cooling setup is powerful enough you should have no problem connecting both machines to 1 radiator. It's almost the same as connecting 2 CPUs in one single machine. You only need longer tubes
Adding the 7800 gt should not provide any additional problems as long as the cooling kit can handle dissipating the heat from all 3 components. Check it's capabilities before you buy, but my guess would be that any water cooling will be up to it.

I'd be worried about static head for the pump, as your pipes are going to be rather long. I'd definitely double check that anyway.
