I'm awaiting arrival of my ThorZone case, I'm an older guy (67) who likes air simming. The GPU will most probably come later, after I see in a few months what prices are then. I tried to start out with an iMac desktop, but it's age (2011) and having to use Bootcamp/Parallels etc. brought that to a disappointing end. I figure a purpose built dedicated machine will be what I want. I'll use the mac for regular computer duties, email, internet surfing. So far I have a VKB F-14 joystick grip & base, Logitech 56 throttle, Thrustmaster TPR Pendular rudder pedals. (When I was in the USN I had a pilot tell me the rudders were critical for some manouvers in the Grumman F-14 Tomcat,one of my favorite planes.) Not being rich, this took a while just like the subassemblies, PSU, motherboard, CPU for this build will have thierpurchase spread out over a little while.
