I have both a Lian-Li PC-60 and a Skyhawk.
How strong does your case need to be?
The Lian-Li is indeed built like a cadillac.
I was particularly concerned with scratching of my drives after I painted them silver, but even this has not been a problem.
I've had it for about a year and ahalf now. You can view it
here.
The Skyhawk is fine too. More flimsy than Lian-Li, but it is neat and does the job for the money.
It is REALLY light, if you need to carry your PC around a lot.
My only complaints about the skyhawk is no room for a decent case fan in rear and front bezel is awkward to remove.
