Case Requirements:
Removable Motherboard Tray
Good quiet cooling
Screwless 3 1/2 and 5 1/4 drive bays
Filters for inlet fans (cleanable too)
Full Tower...well bigger than my current Midi Tower
Bonus:
Space/provision for tidy wiring
PSU installed on the base of the case
Window
Lights
Be made of aluminium (or other strong, light material). Plastic...can be rather tacky if not done well.
Simple, sleek design (Lian Li or similar looking)
Budget. Should not exceed £100
Effectively I'm looking for a case similar to my current Lian Li (I think it's a PC60) but with screwless drive bays and be larger.
