CyberPowerPC - Unleash The Power

Hello, i'm new here but i have doubts in the machine i want. My previous PC lasted about 8 years so i am trying to buy a system that will last as long. As Window 8 is on the horizon, i guess it is a good time to start looking and saving.

1. My main concern is if i needed a Full Tower with all the stuffs i want (see below); i prefer a mini-Silent Tower if possible.
2. I want to use NVIDIA GeForce GTX 680 2GB (same as my laptop), Asus Xonar Essence STX PCI-E Audiophile Sound Card & Happauge High Defination Satallite DVB-S2 TV Receiver, have i chosen the 'right' motherboard?
3. Is 240 GB Intel 520 Series too little, is it easy to just add another SSD in future (Hot-Swap)?
4. Is it wise to get a 3D-ready monitor & Microsoft Touch Mouse instead of the TouchScreen Monitor like
Acer T231H, for using MS OS8?

My budget is £2.5k-£3k. Thanks. Sorry if my questions are silly as i usually buy 'ready made' pc from major brands.
