Is the Vengeance i8300 worth it over building your own?

You pay a premium for assembly, a matched Corsair parts list and a single two-year warranty. Building yourself usually costs less but shifts support and troubleshooting onto you.

Which CPU and GPU does it use?

It uses an Intel Core Ultra processor and an Nvidia GeForce RTX 50 Series card. The exact models depend on the configuration, so check the spec sheet of the build you pick.

Does the 360mm liquid cooler fit other cases?

The iCUE LINK TITAN RX 360mm is a standard 360mm AIO and fits the 5000T case it ships in. Moving it to a smaller case depends on that case's radiator support.

What does iCUE control on this system?

iCUE handles fan and pump speeds, system monitoring and RGB lighting across the Corsair components. It runs as a background app and needs to stay installed for those settings.

It is a 5000T RGB mid-tower, a full-size desktop rather than a compact build. Measure your desk or floor space and check clearance for the 360mm radiator up top.

The system arrives assembled with the 5000T case, the 360mm AIO and the Corsair components installed. Cables and accessories included vary by configuration, so confirm with the listing.
