Hi there, ive got a 240gb SSD all ready to go and wondered if it'll be fine to just slap it straight in to my 2007 imac 20". the installation will be fine but the videos ive seen online (OWC) only seem to be about putting another 3.5 HDD in and not an SSD. I've read or seen mentioned that it may require a case to go around the SSD to make sure it fits but i've recently put and SSD into my oter mac, a mac mini and it all went well with no need for a case. so can i just pop this straight in? your help or links/vids would be greatly appreciated!!! thanks in advance!!
