Upgrade even possible?

[shadowcreaper]

Here's situation I'm in atm.
Please bare with me.
Budget is very much depending on how hard this upgrade might be. But let's say around £300-500 cheaper the better.

My current system as in SIG. is getting very old now. Upgrading graphics card has helped a lot but long term games like bf4 going to need upgrades to work.

My issue Is that I'll need to completely overhaul My system. It's a water cooled system so couple of issues there too.

Here's what I need help with.
Ill need to completely take my system apart to replace all the parts and need a new CPU water cooling block as mine won't fit any of the new motherboards Lol

Picture says thousand words so..

Thanks for replies. I'm looking into how I'm going to upgrade with my water cooling system that I have ( friend put it in) and looks rather scary trying to remove/drain then refill..

Might have to get someone to do it for me. Out of interest why no ATI boards? Intel seen very expensive for what you get.

Thanks though. And yes very tiny
