Hi, I really need help. I just bought a e310 and i want to replace the motherboard. What i want to ask is... 1. Is the e310 proprietary? 2. If so, when replacing the mobo do i also need to replace the case and the psu or just the psu 3. And also what type of case is the e310? ATX, Mid tower ATX, etc Thank you soo much in advance!!!!
