Does MSI AMD R9 380 Gaming 4GB fit MS-7826 (Kaili) motherboard?

I'm thinking about upgrading to R9 380 Gaming but I'm not sure if the mobo fits??? Also my PSU is 500 Watt is it enough? Also my case is 424mm long and the R9 380 is 400mm is it too long then?

Need to know what case your using

R9 380 400mm??? WTF?? my R9 290 Tri-X is 305mm

@PredatorRules: LOL my bad, I read the dimensions wrong on MSI's site. The dimensions are 268 x 138 x 40 mm, sorryy! EDIT : Still don't know what's the length of it though. D:

@04dcarraher: Well, I don't know what case it is, it's package computer from HP, HP Envy 700-402no. Here is all the info about it : http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c04503081

@underi: best way to know if you can fit those workstations a GPU is by measuring on your own with a meter - from the board to the side case panel and from the back to.. well where the card should end.
