Replace “visible liquid-cooling tubes” with “prominent foreground liquid-cooling tubes with clearly visible fittings and coolant channels,” and add “three-quarter close-up framing focused on the CPU water block, radiator, and tubing.” Keep “sharp micro-details” so those components remain legible.

Replace “clean neutral studio background” with “deep matte-black studio background with subtle atmospheric haze,” and change “dramatic yet controlled lighting” to “hard directional red rim lighting with intense cyan spill and deep shadows.” You can also replace “modern high-tech tech aesthetic” with “aggressive cyberpunk gaming aesthetic” for a stronger tonal change.

Keep “custom RGB gaming desktop tower in a transparent tempered-glass case,” “sleek black components,” and “bold geometric graphic accents,” then replace “deep red with electric cyan highlights” with a fixed palette for each variation, such as “violet with ice-blue highlights,” “amber orange with cool white highlights,” or “lime green with cobalt-blue highlights.” Replace the fan phrase with the matching tint, such as “violet-tinted illuminated cooling fans,” so the lighting stays consistent across the series.
