Raidmax Smilodon Casing or Antec 900?! Advice needed, help!

Here's the Raidmax:

Here's the Antec 900 which most are probably familiar with already on these forums:

So here's the thing. I personally think the Antec 900 looks killer and better in comparison. However, this is my first build. While the Antec looks sexy, the Raidmax is cheaper by $30 or so and the side that holds the motherboard tray actually latches out. I've been adding hard drives/RAM/graphics card for years now, but this is my first build from scratch, so the Raidmax sounds easier to work with for a first timer. What would you guys suggest? Is the Antec case hard to work with for someone building their first system, or could it be described as user-friendly (despite the intuition-demanding wire management)? I just love the front grill design on the Antec, but I don't know. Any advice would be appreciated!

Btw, here is what I'm going with:
Gigabyte GA-P35-DS3L mobo
Antec 550watt PSU (already bought)
Core 2 Duo E6750 (I would go with the e8400 except the board requires a BIOS flash and I don't have a spare processor)
2x 1GB 667MHz PC5300 DDR2
Nvidia 8800GTS

And the purpose of this system is to play UT3/Team Fortress 2/Crysis

I have a smilodon xtreme black with green lights. i love the case
its easy to work with and very heavy......but mine came cracked on
both the top and the bottom of the door where they screwed in the wire mesh to tight.... wasnt worth shipping back so i just kept it... I bought mine at newegg also.... But anyway it is a real nice case.

id go with the 900
