There's the one I have that's 0.7 inches larger, the AS4830TG-6808. This one has a newer (and faster) i5 that doesn't suffer from the throttling issues the old 3830TG and 4830TG models suffered from, and the benefit of a (removable, clearly, should you get the right caddy) DVD-RW drive.

I love it, BTW, and if you look hard enough you can find a modified BIOS that undervolts the GPU a hair so you can push some serious clocks (currently running mine at 800MHz GPU and 1000MHz RAM) for some beastly FPS. I took out the optical drive, clearly, and put a SSD in the primary SATA slot and moved the mechanical drive to the optical bay. It's super light for the power it holds and the battery power is unbeatable. I work and game from everywhere (home, work, Starbucks) so this laptop and my USB 3G dongle were great buys.
