Hi, firstly remove the internal slim line DVD drive and get a replacement caddy for a 2.5" SSD (you'll need a SATA power splitter as well to share with the main drive), add in a low profile video card for hdmi and low profile sound card for optical out and then everything else is USB-2 connected - external bluray, PCTV tuner, Bluetooth keyboard/mouse - I also use a "magic eye" type infrared setup as my hi-fi kit is in the cupboard too and I like to use the old school MCE remote sometimes :-)
