In case you were wondering, "Smilodon" is simply another name for a saber-tooth cat. The strange name aside, the Raidmax Smilodon is an excellent case which contains numerous features you'd expect from a higher-end product, but won't maul your wallet.
As looks go, the Smilodon isn't bad. Obviously targeted towards gamers and nerds who prefer putting fancy lightening effects on their PC cases instead of their car, the Smilodon has all the expected gamer-case features, such as numerous LEDs and a large window that allows a clear view of the computer's internals. Get in close with the Smilodon, and you may find that the use of relatively thin metal to be unimpressive, but the quality of the materials used on the front door is far superior to other cases in this price range. The light effects arn't bad either; rather than simply lighting up a fan bay, the Smilodon's blue (or green - there are two different color schemes available) light pulsates through the case's front door.
Looks aside, the key to the Smilidon is how easy it is to work with. This case features a fully removable motherboard tray, and even better, the left side of the case folds out completely with the motherboard still attach, making the addition of PCI cards, RAM, and heatsinks incredibly easy. Drives use a simple "tool-less" system which isn't entirely tool-less, but remains simple and, more importantly, secure. There are many $300 dollar cases that are more difficult to work on than the Smilodon. The Raidmax Smilodon also features numerous fan mounts, a requirement for any gamer's case, although the location of them is merely adequate.
With a price of $89.99 (as of 12/20/08), the Raidmax Smilodon is only slightly below the price limit for a budget case. But the features available justify the extra cash for any user who opens up their PC more than once every couple months. The Raidmax is also often offered with mail-in rebates or combo deals.
