Got mine a few days ago and put a Gigabyte GA-890XA-UD3, Phenom II X2 560, 4Gb corsair DDR1333 ram, three hard drives, Nvidia 9600GT, Soundblaster Elite Pro and Antec 500W psu into it.
Found out that even with the motherboard(ATX), there is a gap between the left edge of the board and the back of the case meaning that my sound card and graphics card when screwed in nearly pulled out of the sockets.
CPU has 3 cores all working ok as the motherboard as auto unlocking.
First time I tried, all four cores were enabled but sound and graphics acted up.
I disabled one of the cores and now it runs great with three.
Only thing I do not like about the case is that the so called front filter is just the perforated front bezel and there is no way of fitting front fan filters.
I looked at the front fan mount from the antec 200 and it looks like it would fit because the 100 and 200 case behind the front bezel looks like they are the same.
