For Micro ATX, i would consider the following,Silverstone SST-PS07B USB 3.0 Precision Series Micro ATX Chassis PC Case
, Cheap and uses 120mm fans so much easier time finding replacement fans for quiet setup. Downside front is plastic, but not a big deal.Silverstone SST-TJ08E USB3.0 PC Case
, Front is metal and very nice looking case (imo), but the frontal fan has to be undervolted, under low setting (900rpm) still very noticeable, below 600rpm starts to be tolerable.Fractal Design Define Mini Series Micro ATX Case - Black Pearl
, another good option, a more traditional style of case, but imo seem very similar to a small atx tower case.
Btw im using a X660 on my TJ08-E (check sig), no issues at all fitting it, but im also not using optical drive, the same would apply for PS-07. If i were to plan on an optical, i probably would have gone with the Fractal mini.
Edit, sorry for suggesting the same, but went to lunch and forgot to hit submit and just did now. Either way i still think either of the 3 as kuzzia recommended are the best option to look for.
