All keys (well switches) are mechanic with keycaps. The idea behind mechanical switches is that they give a key press a more perceptible feel than the standard rubber membrane used in cheaper keyboards. These keyboards are built for durability and gaming experience and include gaming orientated features.

On-board memory and software supplied let you adjust per-key lighting and stuff like macro setup, key delay and repeat rate and various other settings. The Gram Spectrum measures 445 x 136 x 24.5 mm and weight just over 1 kg.

As a zero ghosting mechanical keyboard you won't miss a key strike with the GRAM Spectrum. And yeah the GRAM Spectrum has you covered when it comes to lighting with 16.8 million customizable color options. With versatile lighting effects user can utilize (I think I counted) nine different lighting modes including breathing, wave, and macro lighting.

Mech keys are strong, the keys are rated at 60 million keystrokes for their lifespan. There are also special keys for Keyboard lock, Reset Hotkey, Instant Macro Recording, Instant Profile Switch.

Once opened up you can see the innards, let me zoom in just a little. BTW the red PCB, I now do know why the LEDs configured and activate at WHITE are colored a little pink, it's a reflective side effect of the PCB as good grief... that is a lot of red.

Okay so that IC marked right there as the NXP LPC11U35F-401 is in reality an ARM Cortex-M0 processor. It runs at a whopping clock frequency of 50 MHz (55 when you overclock it (no just joking!). Great and plenty fast for advanced mechanical keyboards actually. On the PCN there also is a Macronix (25L4006E) 4 Mbit 512 KB memory chip to be spotted, which lines up with what Tesoro advertises lol.
