Tons of room for hardware inside both cases

Lian Li has pulled the covers off a pair of new full tower computer cases for computer enthusiasts: the PC-A75X and the PC-A76X. Both cases are made completely from aluminum and have plenty of space for hard drives and other hardware.
The cases are very similar with the difference being that the A75X has a removable front panel and the A76X has a lockable front bezel door.

Inside the cases is space for 12 3.5-inch hard drives. The case also has space for up to three 2.5-inch hard drives. That means the user can install normal desktop hard drives or smaller SSDs without having to use adapter rails. The cases have tool-less features and are all black on the inside. Both the cases are 23-inches tall and 8.6-inches wide allowing for lots of hardware. They also have dual 5.25-inch bays that are accessible from the front.
The cooling system for the cases includes three 140 mm fans in the hard drive bay area, a 120 mm fan at the rear the case, and options for two more 120 mm fans on the top and on the side of the cases. The cases also have dual USB 3.0 ports, dual USB 2.0 ports, and HD audio ports on top.

The A75X will sell for $199 and the A76X will sell for $219. Both cases are set for availability in the U.S. and Canada by the end of September.

Maybe it's the aluminum? It seems to amplify resonance within the chassis from magnetic hard drives. I love my Lian-Li case, but it hums like crazy.

Could be the power supply fan vibrating the case. Hard drives are isolated, most fans shouldn't hum that much and you can get silicone feet for the fans. Or just buy proper fans (at least $8-10 per fan) with proper bearings. Like Scythe or Thermalright fans. Noctua if you want to burn money but they are good.

Aluminum is a part of the issue. If you're going to use aluminum then you better be sure that the thing is solid as hell (ie - Apple chassis), otherwise it'll hum, flex, etc.

My Lian-Li was much louder than comparably priced steel cases that I've used. If Lian-Li put more effort into making their cases less flimsy then they'd be much better. I'm happy with the in-between method of my Corsair 800D, steel construction (and far better internal layout) with an aluminum front.

The reason the Apple chassis is so 'solid' is because it's mostly held together with plastic, like most OEM cases.

Aluminum is a lightweight, cheap, and highly flexible metal. The only reason for it's inclusion in a pc chassis (outside of style) is the thought that being entirely aluminum will help it shed a degree or two of ambient temp (high performance/oc). A case that is 1.2mm thick and still weighs just a few pounds -- you can't be surprised that'll pick up vibrations from anything mounted on it. Then again, that's exactly why there's such a huge 'silent pc' market; ie. rubber fan mounts, rubber psu pads, plastic hdd screws or locking plastic hdd bays, and hundreds of types of fans all with clearly specified cfm and noise ratings (I personally choose fans using a standard cfm/db ratio, with which spire hasn't disappointed me yet).

Personally, I still use my 15 yr old Antec sx1030 built out of solid 1.0mm steel. I think what sold me on the case originally was a review which had a photo of 3 rather obese men standing on a plank on top of the chassis. Since, it's been dropped down the stairs twice (shattering every pcb inside), but still as solid as the day I bought it with no noise issues (hard to imagine some hdd's and fans causing 80-some lb's of steel to start vibrating).

Actually aluminum is more expensive and stronger per weight compared to steel. There is no rational thought that it will provide any better heatsinking but there is the thought that it can be anodized for a more permanent surface coloration, brushed for a more pleasant sheen, that the case won't rust if in a damp environment, and that for an equivalent sturdiness the case will be lower weight.

Regardless, yes your SX1030 is a really solid case, I've owned one as well as the aluminum counterpart made by Chen Ming which is slightly (nowhere near as much as the Lian Li's people are writing about) louder.

While I wish they used 120mm fans, I'd rather have 1mm thick sheeting than all the plastic fancies that modern cases have, though it would've been nice if they had a large built-in front filter panel but that's not too hard to DIY between the bezel and the front metal wall of the case.
