I need a casing recommendation. I'm planning on getting a brand new system built for me (budget: approx 5k for the CPU system (ie excluding monitor, speaker etc)) I was hoping to get the Silverstone Fortress 2, but no one seems to have it available locally. So I need alternatives.

My priorities are as follows (from highest to lowest):

Minimal dust - ie, must have filters in place on all intakes
Size - no bigger than the FT02 (212 x 497 x 616 mm)
Silent (not stealthy, reasonable noise is OK)
Cool (again reasonable, I'm planning on purchasing better heatsinks/ cooler rather than relying on stock functionality)

Budget - really dunno, I know what I'm gonna spend for the whole thing but not so much the individual breakdown. I was gonna ask the individual builders here to give me quotes as I can't build my own system from ground up. But I'll say approx RM800?

Feedback appreciated, thx!
