I am trying to mod my G5 case, which I got for £35. It has no parts in it, so I couldn't even use it as an extra machine (don't worry, I'm sure the previous owner takes great care of the hardware!). I want to use this as my daily case for my desktop PC, simply because I love this case so much. I plan on dual booting Windows and hackintosh OS X (don't worry, I have a Macbook Pro and a Mac Pro). It's really hard to make this ATX mod look good. I have a dremel and various cutting tools, but it just wouldn't look good. I found a couple of sites, which sells these conversion kits, which basically means I only have to cut off a bit of the back and replace it with the new ATX compatible back. The sites are: https://www.thelaserhive.com/product/atx-high-120-kit/ http://www.mountainmods.com/mountain-mods-modular-removable-motherboard-tray-p-56.html The one from The Laser Hive is great, because it's located in the UK, which means I won't have to pay import fees and VAT (£19 import fee and 25% VAT). However, it feels wrong to buy a mod for twice the price of what I gave for the whole case. I haven't been able to find any other alternatives than these two, so I was hoping someone else maybe found someone cheaper. Let me know if you know anyone who sells these ATX conversion kits cheaper than £70. Thanks!
