I built my own PC (as of 2011), the specifications are as follows:
Processor: AMD Phenom II 2.8Ghz x6 (unlocks to 3.4Ghz)

Graphics: Nvidia GTX 460 1GB GDDR5 (HDMI)

Motherboard: ASUS M4A87TD

Hard drive: Samsung 2TB 7000rpm SATA

PSU: Cooler Master 550W

Audio: Behringer USB 2.0 digital mixer

Screen: 32" wall mounted monitor (HDMI)

Case: ATX Gaming PC Silver case

I love my computer to bits, it's really fast and with a 32" HD monitor at the bottom of my bed, I can program with comfort 24/7.

I own a 900 x 1200mm whiteboard which is fixed securely onto my bedroom wall. I often use this in unison with my computer, which is at the bottom of my bed, to plan out projects or jot down thoughts.

A whiteboard is very useful to me, as I often find that I can solve a problem easily by taking a step back and going through all of the processes and methods that I have used and elaborating; I also find that I can just mess about on my whiteboard and spark creativity which can help inspire me to create or add something.
