SilverStone ALTA F1 mid-tower case

The SilverStone ALTA F1 is an ATX mid-tower chassis built from aluminum, steel and tempered glass. It accepts Micro-ATX, ATX and Mini-ITX motherboards and includes a side window with ARGB lighting. Dust filters are fitted as standard. Three 140 mm Air Penetrator fans are supplied for bottom intake.

Maximum graphics-card length 334 mm

The decisive specification for most builders is the 334 mm maximum GPU length. Cards longer than this will not fit, while shorter models install without modification. The removable 3.5-inch drive cage must stay in place to keep the 160 mm power-supply limit; removing the cage allows longer units.

Dual 3.5-inch and four 2.5-inch drive bays

Two internal 3.5-inch bays and four 2.5-inch bays handle a modest storage array; larger NAS-style stacks will exceed the bay count. Seven standard expansion slots plus two vertical slots give room for a graphics card and add-in cards. Top and bottom radiator support reaches 360 mm, while the internal position is limited to 120 mm.
