Best bet is to browse Novatech site. Will give you some idea about bundles, either with PSU and case or just mobos. With or without OS. Take some time to browse.
Find a similar site that will do the same and compare.
Then you can make up your own mind as to whether googling all of the hardware by yourself and construct, or constructing half of it via similar sites as above, and building your own with help. Whatever you decide - good luck.
