Jamesizme :
Currently have a HP Pavelion p6-2303a with the mini tower case after upgrading the PSU and Graphics card the case is just to small not enough air flow and i plan to upgrade most parts in the future
What is a full size tower case i can use that the Mobo will fit in?
That pc has this motherboard: MSI MS-7778
Buy a MSI A75MA E35 which is only 60$ and a very very good motherboard with awesome bios and hdmi,dvi,vga and usb 3.0 and all what you need.For the case I would recommend you the NZXT Source 210. A 36$ cheap case with everything that you need like cable management etc. If you need a case with USB 3.0, go for the elite version of same case which will be i dont know aroun 5 $ more.
