Some of the old timers around here may still have some Chieftec/Chenming Dragons running somewhere. My experience has been that a good case and power supply can outlive several PC builds, while cheap cases eventually fall apart and cheap power supplies fail. Here are the ones that I'm currently supporting.
Silverstone
Fortress FTZ01S (silver) with a Silverstone
SX600-G: It's tiny and cute, but the small volume limits CPU cooling options. The
Nitrogon NT06-Pro is noisier than I would like.
Silverstone
Temjin TJ08-E with a SeaSonic
SS-660XP2: This case and power supply are both great once you've got the PC installed. With some Noctua fans and careful tuning of Asus' Thermal Radar 2 software, the Corsair
Hydro H70 is silent when not gaming.
Rosewill
Line-M with a SeaSonic
SS-660XP2: This case is a bit on the flimsy side, but it's attractive, compact, easy to use and quite inexpensive.
Antec
Mini P180 with an Antec
Earthwatts EA-650: This solid old case has housed more than one PC build.
Antec
P182 (black) with a PC Power & Cooling
Silencer 750 CrossFire Edition (red): This is more old gear that has housed and powered several systems over the years.
Antec
NSK3480 with a SeaSonic
S12 SS-600HT: This case is a royal pain to work in, but it's solid, so it has outlived more than one PC. The original inferior power supply failed and was replaced with a quality unit from SeaSonic.
Antec
P160 (silver) with a SeaSonic
M12 SS-500HM: More old gear that just keeps working.
Antec
Three Hundred Illusion with an Antec
Neo Eco 400C: This case was inexpensive and attractive. An old PC actually went into a newer case after a family member dropped a cheap Rosewill
R6AR6, causing it to explode into tiny pieces.
