Lenovo Legion C530 Cube vs. C730 Cube: Which gaming PC should you buy?

The Legion C530 and C730 Cubes are built in essentially the same case and have some similar hardware options, though upon closer inspection it's clear that they're in different classes when it comes to overall performance.

Legion C530 Cube vs. Legion C730 Cube design and features

Lenovo used the same compact square case for both the C530 and C730 Cube, which resembles something closer to a deep fryer than a classic PC case. Both have handles on top for easy carrying, both have a window on top that gives a glimpse into the hardware, and both have a grate and Legion logo on the front for extra style points.

These PCs are set up with the motherboard in the middle and hardware on either side. On the right side are the processor (CPU) and graphics card (GPU), while the left side holds the bays for hard-disk drives (HDD) and solid-state drives (SSD) as well as the power supply unit (PSU). Panels on both sides of the case can be removed without the need for tools, giving you quick and easy access to the internals for tweaks and upgrades.

The biggest difference you'll no doubt see when it comes to appearance is the internal lighting. The C530 is only available with red lighting and can't be customized, while the C730 has fully customizable RGB lighting with 16.8 million color combinations. If you like all of your PC gear to match, you'll likely have an easier time with the more expensive C730.

As for ports, both have the same basic setup — the video ports will differ depending on which GPU you choose — with two USB-A 3.0, 3.5 mm audio, and 3.5 mm mic on the front for easy headset connectivity. On the back, you have four USB-A 3.1, two USB-A 2.0, RJ45 Ethernet, and another 3.5 mm audio jack.

Legion C530 Cube vs. Legion C730 Cube performance and price

There are a few standout differences between these PCs when it comes to performance. The Legion C530 uses a motherboard with a B360 chipset, which means there's no option for overclocking (even with an overclockable CPU) and it also lacks some RAID support for the storage. The Legion C730, on the other hand, uses a motherboard with a Z370 chipset, leaving it open to overclocking with the available Core i7-8700K and Core i7-9700K CPU options. If you're interested in a RAID storage setup, it can handle PCIe and SATA.

The C530 does start at a considerably lower price (about $748) for a configuration with 8th Gen Intel Core i5-8400 CPU, 8GB of DDR4 RAM, a 1TB HDD coupled with 16GB of Intel Optane memory, and an NVIDIA GTX 1050 Ti GPU. This is enough power for entry-level gaming and should be able to power most popular esports titles with a smooth framerate at 1080p. You can jump up to a $1,063 configuration with a Core i7-8700 CPU, 8GB of DDR4 RAM, a 1TB HDD coupled with a 128GB PCIe SSD, and an NVIDIA GTX 1060 GPU with 6GB of GDDR5 VRAM, which is quite a bit more powerful and capable of running most modern AAA games at 1080p with at least a 60 frames-per-second (FPS) average. Finally, for about $1,250, there's a configuration with Core i7-8700 CPU, 16GB of RAM, 1TB HDD with 128GB PCIe SSD, and AMD Radeon RX 570 GPU with 4GB of GDDR5 VRAM.

The C730 Cube starts at about $1,292, but it has an 8th Gen Intel Core i7-8700K CPU (which is overclockable), 16GB of DDR4 RAM, a 1TB HDD coupled with a 128 GB PCIe SSD, and an NVIDIA GTX 1060 GPU with 6 GB of GDDR5 VRAM. You're going to get similar performance here compared to the $1,063 Legion C530, so the question comes down to whether or not you'll take advantage of RAID support, an overclockable CPU, and the customizable RGB lighting.

Those who want the best performance possible in this type of PC will have to go with the Legion C730, as it maxes out with some serious power. For about $1,880, you get a 9th Gen Intel Core i7-9700K CPU with eight cores and a turbo frequency up to 4.90 GHz, 16 B of DDR4 RAM, a 1TB HDD coupled with a 256GB PCIe SSD, and a new NVIDIA RTX 2070 GPU with 8GB of GDDR5 VRAM. With this rig, you'll have no problem running any modern games at a high framerate, but it will certainly cost you a lot more than the other options. If it's not in your budget, you'll want to go with the C530 Cube.

Grab the Legion C530 Cube for a cheaper option that's not as powerful

Don't care about overclocking, customizable RGB lighting, and RAID support for your storage drives? The Legion C530 Cube can be had for significantly less money and will still offer a stellar gaming experience.

The Legion C730 Cube is better suited for those who want the best performance

You'll pay more for the Legion C730 Cube, but those who want to overclock, set up drives with RAID support, and customize lighting will have their wishes granted here. You'll also be able to get far more powerful hardware for superior performance.
