I'd agree on the SSD and the MoBo, mATX looks massively out of place in a case like that.
Yes, I do regret it now, but its too late for another motherboard. At least its doing what is suppose to do and that's all i need. Even if I add another graphics card, I will have enough expansion ports.
On the other hand, believe it or not, the OCZ Vector is so much faster then the OCZ in RAID 0. I mean I cant really tell by using it, but in benchmarks, the new SSD is over 150 MB faster. The OCZ had the latest firmware on, and it was about the same with the data I found online. I don't regret the switch.
