The Chenming full-tower is very large. It's so large you'd have a hard time finding IDE cables that would reach the top 5.25" bays, in fact, unless you resort to out-of-spec 36" ones. If portability is any concern, that one is the least portable. You get two fan-cooled HDD racks so you can have up to six drives with fan cooling, though. Our PDC is in one of these.
If you don't want so much flash, then how about a plain old
SLK-3000B. It's sort of like what you have now, but no window. No PSU either, just throw your loot in there and you're done.
[*]the SLK3000B can hold more drives than the TX1050B, despite being smaller
[*]it features rubber mounting donuts for the drives
[*]you can cool five HDDs with a 120mm x 25mm front fan (which you have already)
[*]it comes with a 3-speed 120mm rear exhaust.
The main things I don't like about it are the side vents (would rather have none), lack of front audio or Firewire ports, and the door over the drives (removable, however).
The TX1050B uses 80mm fans in front, which will run louder for their airflow, and you can only fan-cool three drives. They are nice sturdy/heavy chassis.
That Asus case looks weird!
😕
So that's my ramblings, hope it helps
