Hello,
 
I have an old pavilion a1654n motherboard which I want to upgrade. To give me a bit of challenge, I found a few possible upgrade, each under 25$.
 
First, lets say my computer isn't stock. I got a E5345 with converter stick, working (no overclocking on my board, I got this modded BIOS: http://goo.gl/qLUU9V , if someone can add overclocking to BIOS would be perfect) and a Zotac geforce 210 overclocked with fan added to it.
 
What I had found is that, if I buy those ebay items, I would be hable to achieve a cheap watercooling:

For reservoir, will use something I already hava at home.
For coolant, I have ton of antifreeze and other things. What would you suggest (Car products, if possible)
For Radiator, I have an old scrap car, will use that.
 
Also, here is another option I found is upgrading RAM:

Now, my question is if I should upgrade RAM or invest in an universal Watercooling method I will be hable to transpose on other boards, and manage to overclock my rig.
