I do like the NZXT Apollo case. I was thinking of getting it for my own rig but I opted for the Antec 300 instead. It just seemed to have a few little extra nice features so maybe that case would be worth a look for you too.
Here's a review for the NZXT Apollo though if you wanted to take a look:
I got thermaltake v3 and very happy with it. Good build quality, black interior, more than enough room and best part - it was only $40 shipped. Just keep in mind that psu in this case will be mounted on the bottom so make sure that your psu cables long enough.
Also remember to include the Shipping in the price calculations as it can really cut into your budget - ie. RAIDMAX SMILODON Extreme Black you linked is $74.99 + $24.99 shipping = $99.98 total !!!) and the NZXT Apollo Black is $69.99 + $19.99 Shipping = $89.98 vs say the NZXT M59 - 001BK which is $69.99 with free shipping and a $20 MIR for a final cost of $49.99 !!
So keep the total cost in mind when deciding as it can make a big difference for example for the same $99 the Raidmax costs delivered you could get the Cooler Master HAF 922 since it has free shipping !!
