Saitek X55 rhino Hotas
saitek cessna rudder pedals
Track ir 5 (which i modded to fit on my wireless heaset with a battery pack,Hate those wires)
steelseries 6Gv2 (Cherry blacks) - ive always had corsair keyboards up to now , with cherry reds, but i think the blacks suit me much more for gaming.
finalmouse (i just did a massive mouse hunt, brought every top mouse i could think of (Deathadder, G400s, roccat KPM, Roccat xtd, steelseries sensai, Perrix 2000 II, Zowie FK1, and the finalmouse) tried them all for a week or so each , and at the end i love the finalmouse.)
Qck Heavy mat.
Asus U7 external dac/amp
Steelseries h wireless headset ( i hate wires when i play)
and when i really want to sound whore i have some AKG K702's (openback reference cans.Vgood but not so comfy) and a pair of K553 pro(closed back great sound but wires....)
also the best things i have are desktop usb fans and some arm rests that clamp to my desk. so nice to game with.
2nd pic is a little old i have different fans (3x 140mm Corsair somethings) in the top now and the cpu cooler is different.
