Umart currently have a Hot Deal with $40 off the, imho, fantastic Fractal Design Meshify C Blackout TG Dark Tint Mid Tower ATX Case Phantom Gaming Edition - looks really good and has top tier airflow to keep system temps nice and cool. I dig the darker tint option and the case refreshingly doesn't have flashy RGB blinkermajigs - which again imho is a good thing.
The "classic" version of the case, i.e. just normal tinted glass and no decals is $139 with Free Delivery from CentreCom

Good case for $139, wouldn't buy it for $149 though. Mainly because the updated Fractal Meshify 2 Compact (which has loads of well thought out features, like removable front dust filter, hinged front door, front USB-C and reworked front panel IO) can be had for $179 (Solid, no glass) or $199 (TG).
