The nice guys at life hacker have put together a DIY guide on how to build yourself a Mac Mini for under $600

lifehacker.com/5815715/how-to-build-a-hackintosh-mini-for-less-than-600

I’ve done a bit of research in sourcing the same parts (mostly from Amazon, once piece from Scan) to see what the equivalent machine could cost over here. My list comes in at £482.24

• Gigabyte GA-H55N-USB3 Motherboard £103.01
• Intel Core i3 Processor i3-540 3.06GHz 4MB LGA1156 CPU £79.99
• ZOTAC nVidia GeForce GT240 512 MB DDR3 DVI/HDMI PCI-Express Video Card £76.63
• 2x2GB Corsair PC3-10666 1333Mhz Dual Chanel 240-pin DDR3 Desktop RAM £29.20
• Western Digital 1TB SATA III 7200 RPM 32MB Cache Desktop Hard Drive £48.11
• SilverStone SG05BB-450 ALL Black Plastic/SECC Mini-ITX Computer Case with SFX 450W 80+ Bronze Certified/Single +12V rail Power Supply £95.96
• Sony Optiarc 8X SATA DVD+/-RW Slim Drive £20.14
• StarTech.com MCSATAADAP Micro SATA to SATA Adapter Cable with Power £8.64
• Mac OS X 10.6 Snow Leopard £20.56

The cheapest Mac Mini starts at £612, but to get one with closer specs to the list above will set you back £855. Bear in mind that installing OS X on your home made machine breaks Apples end user license agreement, so you’re on you own if it ever goes wrong.
