Was fairly happy with AC and my Lian Li V1000 but needed to upgrade cpu and graphics as I do a lot of 3D modeling and other gpu intensive use.
So, I started by adding a 680i board, e6600 cpu and 8800gtx gpu to my existing case.
As this empty interior shows it's a tight little case.



Took about two weeks to realise it needed WC.
Looking through everyones' builds here, I could see I wanted a quad or similar.
However there was a couple of problems.
Neither MM cases or Lian Li 343 were sold in my country and although a couple of intrepid souls had shipped theirs' in it was a total cost blow out at step one. That was not going to go down well with the little woman, especially as the V1000 was only a couple of months old. Still I figured it could go to her if I found a case to suit me.
The other was that switching AC cooling had shown how much I didn't want to have to strip out half the build and motherboard any time I wanted to change a block. Along with that I was hoping to adequately cool quad cpu, dual gpu and chipset in the future, so two loops with all that entailed was to fit in some how.
The more I looked for WC components, the more a PA120.3 for each loop looked right. So a few more of the usual cases were crossed off the list.
As the first couple of 343B builds appeared I could see it was in essence two Lian Li cases joined together and guys were fitting two big rads. Why not do the same?
If my V1000 was only six inches wider there'd be room for everything I wanted and even a small section at the front for my M-cube set up.
The V-Twin was conceived!
I'm currently trying to make it a reality. A very slow process.
