Alphacool Repack Single Bayres 13,30cm (5,25 ίντσες) - Rev.2 (15039)

Water cooling reservoir in a single 5.25" drive bay format, engineered for custom liquid cooling loops where space is at a premium. Its POM body and clear acrylic front provide a durable yet visually transparent solution, letting you monitor coolant level and flow at a glance. Three G1/4" ports—two rear and one top fillport—offer flexible tubing routing and easy filling without removing the reservoir from the case.

Advantages

Compact single-bay design frees up internal space while maintaining a generous ~250 ml capacity. The integrated top fillport simplifies maintenance and bleeding of air from the loop. POM construction resists common coolants and temperature swings, while the acrylic window allows quick visual checks. Standard 5.25" mounting means it fits most mid-tower and full-tower cases without modification.

Suitable for

• Custom water cooling loops in desktop PCs
• Systems with limited internal space or single 5.25" bay availability
• Builders wanting a visible reservoir without external mounting
• Loops using standard G1/4" fittings and tubing
