I was hoping people here could give me a few pointers. I'm good to hook everything up, but I'm not sure about a few things concerning the finer details, and a general sort of critique would be nice. Here's everything I've been looking at:
Case: RAIDMAX SMILODON Steel ATX Mid Tower, one 120mm fan, three 80mm fans
Motherboard: GIGABYTE AM3 AMD ATX Motherboard
CPU: AMD Phenom II 3.4GHz Quad Core
GPU: Radeon HD5750, 1GB memory
RAM: G.SKILL 240-pin DDR3 SDRAM, 2x 2GB
HDD: Samsung Spinpoint F3, 1TB, 7200 RPM
PSU: COOLMAX 650W ATX 12V Power Supply
Everything else I'll be recycling from older computers.
My first question concerns the case and motherboard. This is my first homebuilt setup, though I've tinkered inside some preassembled ones, so I'm confident enough in actually hooking everything up. My problem is that I'm not sure if everything's compatible. How do I know if the motherboard I've chosen will fit in any given case? The case says it fits any ATX form motherboard, but I don't know if there's variations within that to complicate things, i.e. that every port on the motherboard will actually fit a slot on the case.
I also don't really know how good the motherboard I chose was. It seems a bit on the cheap end, yet all of the specs seem decent enough, especially that it has USB 3.0 ports. I'm not particularly well-versed in the finer points, though. As for the power supply, it seems like it has just the right number of peripheral plugins for all the fans in the case, so I'm mostly concerned about the wattage.
Aside from that, an overall review of the assembly would be very greatly appreciated. Like I said, this is the first computer I'll be building for myself, and I'm afraid there'll be some tiny mistakes I'm not expecting that'll prevent it from running. Thanks a lot for any replies.
