+1 for Retention Bracket for sure.
Holy crap Newegg wants $15 for that retention bracket?
Pretty sure I ordered mine for like $6.99.
I used this one on my S1283 model.http://www.newegg.com/Product/Product.aspx?Item=N82E16835233019
Not sure if yours is required for the new version. The Xiggy site is being VERY slow to load for me right now.
