Designed for cooling
Two black thumbscrews (it's always nice when the screws are painted to match the rest of the case) secure the left side panel, but you also have to lift a latch behind the window to detach the panel from the rest of the case.
The large, window-mounted fan is easier to see from the inside, as is its novel wiring job.
Instead of the usual practice of letting the fan's wiring just dangle loosely inside the case, the Spedo's side fan wiring leads to a spring-loaded contact in the bottom trim piece of the panel. The case side of this contact point has wiring that runs to a normal Molex cable, so upon latching the panel in place, the fan is automatically connected to wiring that's easy to access. Nifty.
You would probably expect the Spedo to have a huge, open interior, but you'd be wrong. Instead, Thermaltake uses several large plastic partitions to cut up separate areas inside the case. These so-called Advanced Thermal Chambers wall off the power supply at the bottom of the case, the graphics card in the middle, and the CPU area up top.
The front of the case looks pretty cramped with the partitions installed, but there's still space for four 5.25" drives up top (or three 5.25" and one 3.5" with an included adapter) and three more 5.25" drives at the bottom. Thermaltake also includes an adjustable 120mm fan mount right behind the hard drive cages. A quick-release lock can hold the fan at many different angles and at any height along a rail that stretches across the case's middle seven drive bays.
Once I removed the dividers, I realized just how much thought Thermaltake put into their design. The uppermost one is lined with extremely flexible plastic fringes that will press up against motherboard components but not damage them. The next one is just a semi-translucent plate with a healthy amount of venting right over the graphics card. Next down is another partitioning piece, which this time is fitted to make a tight seal between the power supply area at the bottom and the rest of the case. This one also has some height to it, and as if to make use of every square inch of the case, this piece even has a swing-out drawer. A final plate simply hides the PSU and its cabling, finishing the ensemble with a pretty tight seal.
With the partitions completely removed, the Spedo's interior looks cavernous. Of note on the bottom is the venting under the PSU, separated into two areas with a movable filter that should keep the air entering your power supply clean. As with most nicer cases we've looked at lately, holes have been punched to allow a PSU to be mounted whichever way makes the most sense. Up top, a second 230mm fan is mounted towards the rear of the case along the ceiling. It's just like the one on the side panel.
The hard drive cages are easy to remove from the case thanks to wide plastic levers and well-machined steel tracks. It's always nice to be able to put a computer together with minimal reaching for the screwdriver, but you never want to risk your hard drive's safety, either. Thermaltake tackled the problem by designing drive sleds with four plastic rockers that each fit where normal HDD mounting screws go.
When the sled is inserted into one of the cages, the rockers are pressed in tight and the drive is secured by the prominent gray latch. I took the cages out to showcase their design, but you can remove individual sleds just as easily without pulling out the entire cage.
