Hello,
I'm using an HP Pavillion HPE Phoenix H9-1100z with an updated PSU.
I'm going to replace my case because my current one is very cramped. (I had to remove the optical drive bay to get the molex cable to the hard drive)
I'll start off with my specs:
CPU: AMD FX 8150 (Stock speeds, stock cooler)
Motherboard: Gigabyte 2AC8 (Can't find any info on the form factor, so I'm not sure what cases are compatible, unfortunately)
Memory: 10GB (2x4gb, 1x2gb) unknown brand, 1066MHZ
Hard drive: Hitachi HDS723020BLA642
Graphics card: AMD Radeon HD 7950
Power Supply: SeaSonic M12II Bronze 620w
My budget is $150. I'd like it to be as cheap as possible though.
I really like the way the NZXT Phantom series look (Not so much the 410 and though, don't like the thing which sticks out at the bottom), so I was looking at the 530 (My personal favorite looks-wise in my budget)
Another thing to note is that my case has a tiny (5 inches at most) extension block thing for the rear audio ports, would this work in a new case or would I have to buy cables?
I've also never replaced a case or anything before, so would the fact that I'm using a prebuilt motherboard without a manual or marked cables make it difficult?
If you need any more information just ask.

Although the features on that case look nice, it looks a bit tacky in my opinion. What are the differences on the Phantom 530 vs it?
