Some of the new Thermaltake cases look nice - and the suppressor cases have a very nice but Spartan exterior and do a good job of cutting down the noise.
Same with some of the Fractal Design and Corsair cases.
You really didn't give any parameters like budget, size, features, etc.
I would second the Fractal Black Pearl R4. I had one for my 2nd storage server till I needed more bays and I really liked it. Never had a problem so don't know how Fractal's support is. The case is all sleek blackness with some foam for sound dampening. Room for 8 drives but you can actually remove 5 of the bays if you want room for big GPUs or anything else. It only came with like a couple of fans but there are spots for many more fans. I live where its hot so I ended up maxing out the fan mounting points and it was not so quiet but cool enough to run without air conditioning 24/7. My memory was it was really easy to build on with good space behind the motherboard and cable routing. My main complaint, and that is only in a modern context now with 200mm+ fans for quieter operation, is that the R4 fan mounting options were for smaller fans.
Coming from two P180Bs, I ended up slimming down a tad into a Lian-Li A05FNB... I lose some HDD slots, but stuck an icydock 5.25" disk sled that now holds 6 2.5" SSDs in my box. I still have one internal 2TB HDD for backing up critical data that resides on the SSDs on a nightly basis.
I have liked the fractal cases, but I just couldn't do anything that large again... I tried to even go MicroATX for this build, but still needed more PCI-e slots than those offered.
