Just with all the other HYTE cases, the metal side comes with a full plastic layer that holds a fine mesh dust filter which lines up with the unique air-vent design. That said, the design of the one found on the Y70 is shaped like sun rays, whereas the panel on the Y60 is symmetrical in design. You could absolutely disassemble the case by removing all glass panels as well. This is really helpful if you are planning an elaborate build, but for most - including us, the access through the main side panel is more than enough.
The expansion slot setup aside, the layout of the Y70 is essentially similar to what we have seen with other dual-chamber cases. That said, HYTE has also managed to make all the bits and pieces within the chassis look unique. There is the asymmetrical cutout for the CPU cooler backplate and the large brand logo on the HDD cages you can clearly see when the chassis is empty. On top of that, HYTE has printed the labels for the screw setup unto the motherboard tray, which is a nice touch. The backside chamber feels a bit roomier than that of the Y60, thanks to the Y70's larger size. There are plenty of hooks for cable management as well as similar grommets which we have already seen on the Y40.
You will find another area on the side of the chassis that can hold three 120 or two 140 mm fans. It is far enough away from anything so that even a thick or push/pull radiator assembly of up to 360 mm size will fit without interfering with any other components.
The floor of the Y70 is one big air vent and there are two openings for cable routing. It is unfortunate that these don't have grommets of some sort, as you will see this area when viewing the system from the front, even with a GPU installed. In the ceiling you can see that the case utilizes the entire length of the case for cooling purposes, with the mounting holes for such units quite far away from the motherboard.
Towards the rear, in the main area of the Y70, are the aforementioned expansion slots. The PCIe riser cable is perfectly embedded into the floor of the chassis, right above the possible fan placement. On top of that, the connector for the motherboard is encased in a color matching, red shell with the company branding and another 45° design element. Above that is the previously mentioned vent which can take a fan or radiator of up to 140 mm in size.
In the rear, behind the motherboard tray, you will find the two hard drive cages. Each of these can hold either a single 3.5" drive or two 2.5" units. As such, if you stick to the smaller form factor, the HYTE Y70 will allow for a total of four such drives to be installed. The PSU bay is simple, with a support tray in red. This space allows for units of up to 230 mm in length, so you should have no problems opting for high-end, high-efficiency variants.
Viewing the side mounting possibility for cooling from behind the motherboard tray, it becomes apparent that any such units will have to be mounted on the interior of the case. HYTE has placed a barrier to the right to ensure that cool air from the exterior is pulled in instead of air from the interior of the chassis. While the Y60 had two individual grommets, the Y70 has one massive L-shaped piece with four deep openings so that you can make sure the interior of your system has the possibility to look spotless. On the floor of the case, there are three black Velcro strips for even more cable management flexibility.
The HYTE Y70 uses a unified motherboard header connector, so you don't have fiddle with individual pins and wires. Additionally, you will find the USB 3.0, USB-C and audio cables, all of which are sleeved black and use the usual connectors.
