Ok, so i need about 3 fans (2 front for intake and 1 back for exhaust).
For the monitor is AOC a good brand? Because their monitor are cheaper then many brands like samsung or asus. For example this one
AOC G2460VQ6 Monitor Gaming da 24", FHD, 1920x1080, 75Hz, 1 msec, Speaker, D-Sub, HDMI, DP, Nero
cost about 129€ while an asus one cost about 182€
Is it a good choice? I like Fps games but a 144hz display is about 280-300€ and 75hz is fine for me
