I recently bought an Antec SLK-3700AMB from Newegg. Overall, I'd say their design is quite nice - filtered front intake fan (120mm, not included), and a 120mm exhaust fan (included). This can make for a quiet case. I do have some issues with it:
- The slim drive rails don't work quite right with my Sunbeam Rheobus. I had to take a Dremel to the fanbus to get it to fit in the case.
- It uses weird clips for the fans. This prevented me from using the Vantec noise dampeners I bought, as the clips don't permit the extra thickness that the dampeners add.
And because of the clips, should you choose to slice out the stamped fan grilles in favor of chrome wire grilles, you'll be left only with the plastic guards provided by the clips themselves, which still permit a finger to contact the blades. Not too much of an issue, as the only "exposed" fan is in the back of the case, but I still would have preferred standard spacing screw mounting holes.
- It has one power LED and 3 hard drive LED's. Problem is, the three drive LED plugs are each simply labeled "HDD LED" with no indication as to which one goes to which LED. This must be determined through experimentation.
Other than those issues, I do like the case. It's got a cooled, removable 5-drive cage right next to the intake, which is perfect for my 4 disk RAID 5 setup. The paint finish is excellent too. It comes with a 350W power supply, which if you need, it should do fine. If you don't need it, it's an instant rebate.
I looked at the P-160 too, but found that the SLK-3700AMB offers a good number of the same features, such as the efficient airflow system, but it costs about half what the P-160 costs. Granted, that's because it's steel, but I figure that a computer case is going to be quite heavy after it's loaded anyway, so what do a few more pounds matter?
