I need some help purchasing some stuff

[Toho]

so I recently made a rig for myself, details below, but I have yet to buy a wireless card/adaptor, a monitor and some converters.

I need the converters because my case has 4 built in fans and the neither the case or the power supply provided me with the necessary wires to hook them up.
excuse my noobish terminology but the fans have 3 little holes, I only found one spot on my motherboard to hook it up but that caused my computer to short-circuit (?) and turn on and off every 4 seconds.


for the wireless thing, I have 2 choices, a card or the adapter but my friend told me to buy a very good adapter instead of a card because a card would needlessly heat up my system. my modem is in the kitchen and so it is a little far (considering it is a modem); maybe 10 or 12 feet...
any suggestions on which one to get and what?

finally the monitor, I changed my mind with the other thread, since I am paying for 15$ shipping i might as well order a bunch of stuff. so what monitor would you recommend? my price range is below 150$, I am going to be staring at this thing day in day out (my work, gaming, tv, etc) so it should be a LED and I should be able to play around with how/where the screen is facing. I dont want it to be fixed in only one position/tilt... then again I dont want it to be doing a 360 in 5 directions , as long as i can tilt it back forth it should be fine.


Thank You
oh and btw here is my system.

Only the cpu cooler fan draws power from the motherboard.. the case ones need the psu

2 of my case fans take power from the board.

get your parts from NCIX if your in canada shipping is far cheaper Newegg CA still ships out of the US so shipping on a case is double same goes for some other parts as well.

also far better case and its cheaper the Antec are seriously over rated garbage

I have already ordered the stuff and assembled them.
so thats done with but what do you think? This is my first time making my own computer and the parts were chosen based on my budget and reviews I found on new egg.
do you think this build is strong enough to run R2TW and other high end games in the next 2 or 3 years in decent quality?
