Actually Hitachi HDD like pretty reliable leh according to BackBlaze. See:

But DIYers always prefer WD. How much worse is Toshiba to Seagate?
I'm curious why Vios casings are bad. The layout? Size? Material used? Non-removable drive cage? Top-mount/bottom-mount for PSU? Tool-free design?
Are certain casings or design better or worse at heat retention and dispersion? Due to material or air intake vents? More mesh + fans = better airflow and cooling?
To me as a noob, casings all look and perform similarly. Major consideration and difference is what size motherboard is supported (atx or matx or mini-itx, slim or regular)
I wont comment much on hdd. Cause i myself very suay on hdd. But most failure rate will go to toshiba.
For chassis. There is a difference between a cheap chassis to an expensive chassis.
Just my general rule on chassis. Anything below SRP of $128 is consider cheap chassis. Anything above will be better in terms of,
1) Material used. Cheap chassis tends to have lesser alloy mixed. It tends to bend easily if it has not been handled properly. Also certain chassis has more plastic over metal.
2) Aluminium chassis such as Lianli chassis is full alu. They are usually tooless and very easy to work with imo. Strong, and very solid finishing. Usually quite expensive also.
3) Features. Things like expansion slots. Can it accept dual/tri/quad sli or xfire? Features like noise dampening materials. Etc
4) Removable hdd cage. Good for mid tower size. Making more airflow and also able to get bigger clearance for longer gpus. Such as Sapphire TriX, giga windforce and any other models that have 3 fans such as triFrozr by msi.
5) Rubber grommets. Rubber grommets helps in making the wires look neater and best of all stealth.
6) Sufficient ample space to wire manage at the back. Big enough and able to close the lid back without any difficulties.
7) Ability to mount Radiators. Such as 240mm 360mm or 280mm 420mm radiators.
