Hey guys just need some verification that all the parts I chose are compatible. Just double checking as it's been awhile since I last built a system.
I plan on using my current lcd monitor and keyboard/mouse.
Also If anyone could point me in the right direction in terms of wireless internet access that'd be great.
If you have any suggestions, please let me know. Just note that I have a 850 dollar budget.
Thanks so much in advance.
