In order to reach the fans behind the front panel, we must remove the panel first. The panel is taken off by pulling it on the bottom and release it from the latches. Note however that the top panel should be removed first, otherwise the front panel latches could end up broken, picture below. Cooltek did not explain it in the user's manual, so users should be careful when removing the front panel.
Beneath the mesh is a thin layer of foam that acts as pre-filter, while the real mesh filter is in front of the fan.
The fans are taken out with the filter. The black/white version of Skiron comes with whide LEDs. The LEDs are in the front panel fans and on the top panel fan.
Power and reset keys are on the angled part on the top panel, so they're easy to reach if you keep your case under the table. Next to them are two sliders that control fan RPM.
Coltek's C.A.M.V.C. (Cooltek Advanced Modular Ventilation Concept) uses two channel fan rpm regulation with support for up to six fans. Skiron comes with four fans.
Skiron has six USB connectors. The top panel holds two USB 3.0 and USB 2.0 each, as well as audio out/in jacks.
Two USB 2.0 ports are hidden in a cleverly implemented compartment. It surely can't hurt because while USB sticks are tucked inside, you can be sure kids won't even notice it and you won't accidentally hit it and damage it. The compartment was large enough to take Corsair's pretty thick USB stick, which means that you're well covered.
You should be careful while taking the front panel off in order not to damage the USB ports.
Cooltek left another open compartment behind the I/O panel and you can use it for sticks, keys or such.
The top panel holds a 17cm fan (max. 900RPM). We got the fan mounted inside the case, but you can easily do it outside, in scenarios where you may need more room for a large CPU cooler.
Removing the top panel is done by pulling the back of the panel upwards. We were afraid we'd break something because the latches wouldn't let go easily.
On the bottom of the case, underneath the PSU slot is a removable filter. The second hole you see on the bottom of the case is another fan exhaust with a mesh over it.
Skiron has seven expansion slots. The expansion cards need to be screwed down and Cooltek provides thumb screws. The back panel comes with a 12cm fan.
