Don't go for the Cosmos S. Seriously. Not enough headroom for hi-perf air coolers like the True or any towers. The default fan on the side panel is noisy like hell., no reset, touch sensitive power button on the top near the USB port (accidentally gets touched all the time
) and tough it looks as if a 3 fan RAD can be hooked up on the top ( I did that), it's a real tight squeeze.
Whatever w/c parts u get, no Cosmos S. Take it frm someone who's spent the bux and regretting it (it's so damn expensive, it's difficult 2 find a buyer too).
