Don't let the fangs on the front scare you; the Smilodon is a monster under your control. Its innovative design features speed assembly and get you back on the hunt in no time. Once you're up and running, the plethora of fans will keep your system cool even in the hottest of firefights.

System setup is eased by having the mobo tray attached to the right side panel. Undo the locking screws and remove the side panels and you have a totally open chassis. Install the mobo and expansion cards to the side panel along with the CPU and memory then all you have to do is put it back in place as a unit. But first install all your drives in the tool-less racks. When both sections are assembled all you have to do is connect the wiring.

There are fans everywhere to keep your components cool. A 120mm fan is mounted on the back panel for main ventilation. The side panel has an 80mm fan to boost CPU cooling. There is a retaining bar designed to help hold your video cards in place, and that too has an 80mm fan vented to the outside.

1 out of 5 eggsdisappointing

Pros: 4 fans and led lighting

Cons: TERRIBLE cable management
No 2.5inch ssd mounts
power supply only has one 6-pin pci-e
front door magnet very weak, does not hold it closed

Other Thoughts: Included power supply may work for casual web browsing but I would not use any psu that came with a case. Had to take it out because it would not power my video card. I also may just buy a whole new case because this case is not pleasing to look inside. With no cable management a jerry rigged zip tie nest is the only option. please go find a case and psu that will look much cleaner. this may have been a decent case 5 years ago but you can get a much better one today.

4 out of 5 eggsNice case.

Pros: Very well Built, comes with a fair amount of hardware, looks great, stays nice and cool.

Cons: CABLE MANAGEMENT. If you decide on this case you should be proficient in the use of Zip-ties. You will be using a lot of them.

Other Thoughts: Would be great if it came with 750W power supply.

5 out of 5 eggsGreat Case - Great Value!

Pros: I absolutely love this case. I've had it for almost a year and a half now and I couldn't be happier. It comes with a 500w power supply, has an extra parts container in the bottom, and 4 stock fans. I have been so pleased with the design of the case and how easy it is to open the case and lay the motherboard down flat for easy installation/troubleshooting. I have always kept the case with the fan side to the wall of my desk (and relatively close to give me more leg room) and it has kept my rig cool, even through the heat of the summer months.

Cons: The only problem I have had with this case is the power cord which just decided to not work one day, but I had another lying around and was able to easily replace it. I believe the power cord may be slightly too thin to carry the necessary amperage to run the PSU, but this is just a guess. Also, the magnet in the front which holds the door (the front panel covering the power button, disk drives, etc) must have lost a poorly attached magnet because it does not stay shut when I need to physically pick up my case and move it. However, this is really only a minor issue and could easily be fixed with a new magnet and some glue, but it just doesn't bother me enough to bother with it (I keep the front door slightly open at all times to access the power button).

The 500W PSU is at the low end of many minimum video card requirements.

Other Thoughts: This is seriously one of the best cases you can buy for the money, especially considering (nearly) anything comparable comes without a PSU, and is ~50% more expensive. This is a solid case, and if you're looking for great functionality and super easy access to the motherboard, this is the case for you. Other reviewers mentioned how the cables get caught on things (corners in particular) when opening the case, and this is true, but this is a direct result of how the cabling is laid out during the initial build, and not a result of poor case design. I too have had some cables snag on corners when opening my case, but if you're careful (as you should be with sensitive electrical components anyway..) you will be just fine. Although I had an issue with the power cord, it's really not something the OEM is at fault for, nor could it really be controlled for. The PSU is 500W which is the minimum for the new GTX970 series so this case can save you ~$100 on a new PSU. Seriously, pick up this case, you won't regret it!

4 out of 5 eggsIt's ok...for the price

Pros: It's a case. It comes with fans and a power supply.

Cons: The MOBO panel folds down for easy board installation--but you can't mount the heatsink on it until the side is closed. The power supply makes installation of the heatsink a little difficult--and the power supply itself sucks. Cables...everywhere...

Other Thoughts: It was a great case for when I built my last computer, and provided a great case to re-build a friend's old machine in for her to give to a friend who needed a computer (and didn't want to cut themselves on her old case). I'd suggest it to anyone who wants to save money...but...for the price: you can go a little more and have a better case and power supply.

1 out of 5 eggsRaidmax case & power supply

Pros: Case is OK....stout and works OK

Cons: Case front is weak & latches poorly but works.....power supply will not turn on when connected to the turns on OK when bench tested......the power supply I replaced it with works just fine.....tied the Raidmax power supply with the MB again to be sure and it still did not work....Power Supply will not turn on inside the computer.....Raidmax Tec Support is saying I didn't connect it properly......I have been doing this since 1984 and I haven't missed much in terms of computer problems, so I don't think it is me....

Other Thoughts: Just be aware of the value you are getting

4 out of 5 eggsGreat case

Pros: This case is looking good! Nice green lights and details on the inside and outside. Lots of fans to keep it cool and a bunch of tools and utilities to help you build/re-build your computer.

Cons: No cable management.

Other Thoughts: I bought this for a friend to upgrade his computer. He needed more room for a new GPU to power up his games, and this case was the perfect fit.

Good budget, nice looks and room for stuff. Recommended!

3 out of 5 eggsLong in the Tooth

Pros: Heavy steel. Durable. Cool lights if you like that sort of bling.

Cons: Outdated. Cheap fans that are poorly placed. Case released in early 2008. Much more modern options out there. For same price you can get a Corsair, Fractal Design, Phanteks, etc

Other Thoughts: It was a good buy for me in 2009. Passed it on to my son in late 2012. Buying him a Fractal Design R4 for his birthday. The Smilodon will live on when sold to one of his friends .

5 out of 5 eggsUpdated Raidmax case review

Pros: Okay, so I built the new system and am 100% loving the case! Here's what I did not read in the reviews:

There is a small utility box under the HD cage - holds the screws and HD brackets. These brackets, BTW, are the bomb, super easy for tool less install! There are 8 brackets for 4 drives and click in place solid!

HD cage swivels out so drive install is easiest I've ever experienced in 20 years!!

My fist tool-less case and I am sold on this option. I think if you will move the case around a lot, you may want to use at least a screw or two though...I wouldn't trust it unless the computer is going to sit in one place.

The hinged sides are messing with small screws at all.

Plenty of room to get your hands in for organizing cabling.

Cons: Case fans could've had longer power cords, but not a big deal at all.

Other Thoughts: Had to use a screw to tighten media card reader in 3.5" bay, but I figured that before install as they are always a bit small and loosely fit. Tool less option just didn't work for that piece; again, from years of experience, I knew that would be the case.
