After a lot of searches; I CONFUSED SO MUCH...

I bought SAITEK X52 PRO FLIGHT CONTROL SYSTEM & SAITEK PZ35 PRO FLIGHT RUDDER PEDAL from turkish suppliers with a amount of 526 TL (1€=2,3 TL) it is approximately €230.
Yesterday I ordered Velleman K8055 USB interface with amount of 100 TL == €44... (supplier called me and said that this card is our of stock!!)
I also bought 2 pieces of 1kw DC motor 3000 rpm with a 1:90 gear box and get 2 mitsubishi inverters.
Tomorrow 2 monza racing seats will come and will give a gift one of them to my friend deniz elmas
For the computing system I dont want to use 2 different computers. Because of that I ordered special computer which is ASUS
INTEL İ73770K 4.6GHZ 16GBDDR3 2TB+128GB SSD BLU-RAY 2GBDDR5 GTX680VGA WIN7... (24/11/2012)
For the chasis or hardware of the simulator is not problem... No any serious cost will be occur, all materials from my warehouse

It will me my first simulator and firstly I was thinking to build 360 degree 2 DOF motion simulator like the brasilian guys have done... But know I dont think to produce it firstly...
Maybe to produce joyrider will be best for *..
What is your opinions...
Please give me some suggestions...
