PC water cooling reservoirs are normally purchased as a unit, fully assembled and ready to put into service. As a custom builder though, anything can happen. Parts can get lost or damaged, or a new idea can strike that requires separate parts without needing an entire reservoir. Reservoir parts and accessories include everything from tube tops to mounts to lighting to the actual tubes used. TITAN RIG offers a broad selection of reservoir parts and accessories from several brands, allowing you to buy only what you need to get on with the job.
