I was able to get my hands on a empty slim PS3 housing from an old GameStop PS3 demo display about 4 years ago. I have had building a PC in a PS3 idea pigeonholed for quite sometime. So this year the perfect storm happened. I had enough spare parts laying around and finally went through with it.
The parts choices were made around my spare CPU and 2.5 HDD (Actual out of pocket cost is around $220). With a little hot glue, screws, and a little ingenuity I was able to create my little Frankenstein.
(It most likely will be booting
Lakka launchbox's BigBox via Windows 10 shell launcher and become a emulator console. Not 100% decided.)
There are few quirks but all and all I'm proud of it. I need to figure out a better power button, some sort of better cooling (temps hovering around 50c at idle, 74 on load with TF2) Eventually I would also like an entry level GPU too (like a 750ti) but not sure yet how I'm going to do that.
Why... (Because I like weird stuff)
CPU* - I picked the G3240 mainly because I had one available from an upgrade on another machine.
Cooler - The choice behind the cooler was purely because of height restrictions and cost. The stock cooler was just to tall and I wanted to keep the exterior case modifications to a minimum.
Mobo - I wanted a sub $100 motherboard, with WiFi, and support for future upgrades in the next year.
RAM - I wanted a minimum of 8GBs and cheap so this choice was a no brainer
HDD - Yes I know it's a 5400 RPM drive, why... because it was free (from a PS4 that I upgraded) and 2.5" (size restrictions)*
PSU - the only item I'm on the fence on if I made the right choice or not. I kind of wish I went smaller with a Pico PSU but it's nice having a fan on it creating some air flow in the case. Also the 80 gold + is nice too.
Extras - the front USB 3.0 are nice to have for controllers and it's just cool having the LEDs light up on the front. The power switch is the only thing I know for sure that I am going to replace hopeful with an original PS3 power switch board.
