Noticed a few people mentioning there Thermaltake cases. I have had two of these in the past, My first custom build pc was a thermaltake shark. I loved them, ahh the naivety 
I went on to buy a thermaltake kandalf LCS, I hated it. The holes didn't even align properly for the resevoir and pump, this was a well known problem! I had to drill other holes and "make do"
The case gathered so much dust in the front panel and there was no way of cleaning it off without taking the whole panel and radiator off. It was stupidly heavy at over 20KG empty. The pump blew up last month and I replaced the whole case with a CM690II Advanced. Wish I done it years ago, also had to buy a new cooler, got the Coolermaster V8. Allowed me to push my quad to 3.6 easily, which the crappy built in cooling on the Kandalf wouldn't allow.
I will never buy Thermaltake again.

There must be something wrong with your system....SC2 isn't that demanding.

Nothing better than a slideshow at minimum settings.
