I have built my own desktops since the mid 80s but never got into case mods such as yours CERVER7. My intent has always been to build the fastest computer I can for a reasonable cost. It's surprising that I can still do that using the same case and just upgrading the motherboard, CPU, memory, and videocard even today. My last build was several years ago with an ASUS board and an AMD dual core X4200 CPU. I installed a Radeon 9800 video card and was pretty well set for a while, even in frame rates for games. I moved to an HD2600 to get HDMI. Frame rates stayed about the same with that card, but I gained direct LCD compatibility.
Now, I am looking at the I5-750, Gigabyte P55 MB with a Radeon 5750 video card. I need to upgrade the ram again for that board.
My goal is always to build something better and faster than I can buy at retail for the same or less money. Gaming and video ripping drives my upgrading desire. I'm a Maximum PC subscriber since the early 00s. I'm still a budget builder, though
