Asus ROG Z11 Mini ITX Chassis Review

Rating: 7.5.

Asus ROG Z11 is pretty much the opposite of what you might expect. It supports Mini-ITX but is larger than a number of ATX cases and it can be stood upright or laid down so you are never quite sure which side is front, back, top or bottom. One thing is for certain, which is that your graphics card will be displayed behind the window at the front (or top) so you had better have some tasty hardware for the world to enjoy.

Getting inside the ROG Z11 requires a certain amount of thought as the rear panel has a hidden thumbscrew and the panels lock together in such a way that you need to remove them in a particular order.

One you have that figured out you will find that building a PC in the ROG Z11 is slightly confusing as the motherboard is rotated 90 degrees with the rear I/O panel pointing upwards towards the two 140mm exhaust fans. We chose to use an SFX power supply to create as much space as possible in the floor of the case and this was tricky as the EPS cable would barely reach the connector.

The problem here is that SFX power supplies come with cables that are intended for use in a small ITX case, yet this particular ITX case is very large. After a bit of a struggle we had the cables connected but were unhappy with the cable routing behind the motherboard tray.

Another quirk of the build is that the graphics card hangs vertically at the front of the case which works perfectly well but looks unusual. Once the hardware was installed we were ready for some thermal testing.


To put this case through its cooling paces we will be using a test system consisting of an Intel Core i9-10900KF, Palit RTX 3080 graphics card and an SSD. This system allows us to produce a substantial amount of heat and effectively test the Asus ROG Z11‘s cooling capabilities.

Test System:

  • Processor: Intel Core i9-10900KF (10 cores/20 threads, 4.9GHz all cores)
  • Motherboard: Gigabyte Z490I Aorus Ultra
  • Memory: 32GB Corsair Vengeance LPX DDR4-3600MHz
  • Graphics card: Palit RTX 3080 Gaming Pro 10GB
  • Power supply: Corsair SF600 Gold
  • SSD: 1TB WD Blue M.2 NVMe
  • OS: Windows 10 Pro

Custom Loop Cooling

  • CPU Block: EK Quantum Magnitude
  • GPU Block: Alphacool Eisblock Aurora Plexi GPX-N
  • Radiator: EK CoolStream SE 240mm
  • Fans: 2x EK Vardar EVO RGB 120mm 2,200rpm
  • Pump/Reservoir: EK XRES 100 DDC MX 3.1 PWM
  • Fittings: EK 13/10mm Quantum Torque
  • Tubing: Corsair XT
  • Coolant: EK CryoFuel Solid Scarlet

Cooling Performance

Cooling Performance Overview
With the fans running at full speed (and rather noisily) we saw temperatures that were quite acceptable but slowing the fans to 50 percent made a significant difference to the results. While we can see the ROG Z11 is configured like a chimney, we have to think the power supply shroud and other pieces of PC hardware obstruct the air flow to such an extent the ROG Z11 works rather poorly.

Closing Thoughts

We spent a fair amount of time working with the ROG Z11 yet it continues to cause us a fair amount of bafflement and confusion. It seems to us that during the development of ROG Z11 the main priorities were the novel form factor and aesthetics, and there is no denying the combination of aluminium, tempered glass and RGB works well.

We quite like the way the graphics card is suspended in the front window as our liquid cooled RTX 3080 looked superb however air cooled graphics cards may well be starved of cooling air. As we know, Asus manufactures some of the largest and thickest graphics cards on the market so it is quite possible that an Asus graphics card would be a poor choice for the ROG Z11.

Another curious point is the way the Asus design team decided to give the customer the option of flipping this tall ITX case into the horizontal laid down orientation. We are all in favour of choice but this orientation has a significant effect on temperatures inside the case and also means that Asus had to include a short adapter cable for the main power cord as well a plate to rotate the Asus ROG logo by 90 degrees.

In a sense these are quibbles about details as we imagine a small part of the KitGuru audience will be wowed by the Asus ROG Z11 while the majority will have little interest in a big and tall Mini-ITX case that presents the owner with a number of problems.

While we are mildly amazed by the price tag of £240 we wouldn't be the least bit surprised if those potential customers quite like the high price as it will buy them exclusivity and they will be the only person in their circle that owns an Asus ROG Z11.

Well that's fair enough and we hope they enjoy the aluminium panels, glass and RGB as the Asus ROG Z11 has a certain amount of style but we can think of a great many cases on the market that do a better job at a lower price.

  • Plenty of space for a full sized graphics card.
  • PWM fan hub is included.
  • Smart and unusual styling.


  • Asus ROG Z11 is rather expensive.
  • This large case is limited to a Mini-ITX motherboard.
  • You need fast fans for decent cooling and that gets noisy.
  • SFX power supply cables are very tight.
  • Cable routing from rear I/O is awkward.

KitGuru says: Asus ROG Z11 is interesting but we can see no clear reason to buy this large and expensive ITX case.
