So what I want to do is move my current PC parts from the full size case I currently use to a SFF case - really just as small as a case can be while being able to fit what I need. I don't need any actual upgrades aside from the case switch. It's not used for intense gaming or any CPU/GPU heavy tasks. I want the new case to be as silent as possible while on a tight budget.
The current PC:
Processor: Pentium4 550 HT 3.4 GHz, 800 MHz Front side bus, Socket 775
Motherboard: Asus PTGD-LA
Memory: 2x 1GB PC4200 240 pin DDR2 SDRAM
Harddrive: 1x 250GB SATA
5,25" units: 1x DVD-RW, 1x HDD SATA dock
Graphics: Nvidia GeForce 6800GT 256MB
What I think, and hope, is possible to bring to the new case is the CPU, RAM, HDD, DVD-RW, HDD SATA Hot-Swap dock. Essentially I want the switch to be as cheap as possible.
I've found the graphics card to be obnoxiously loud, so I would rather get rid of that. Something of equal performance or slightly above is desired; would still like to be able to play HL2 and Portal.
The problems I can imagine with this switch would be maybe not finding a case where one can fit two 5,25" units. I don't keep an eye at the news in the PC market so I'm not really sure what to get or more importantly what parts are compatible. I'd rather buy used parts, where possible, because of the cheaper cost.
Any recommendations for cases, compability and other things I should think about? Am I perhaps going in an entirely wrong direction - is there a simpler solution?
