New Computer 2

My neww computer came in last week. Here’s what I got:

- HP Pavilion Elite d5000t ATX PC
- Upgrade to Genuine Vista Ultimate with Service Pack 1 (64-bit)
- Intel(R) Core(TM) 2 Quad processor Q9550 (2.83GHz)
- 6GB DDR2-800MHz dual channel SDRAM (2×2048, 2×1024)
- 768MB NVIDIA GeForce 9600GS, DVI-I, VGA, HDMI
- Wireless LAN 802.11a/b/g/n & Bluetooth(R )
- FREE UPGRADE to 750GB 7200 rpm SATA 3Gb/s hard drive from 500GB
- Blu-ray writer / HD DVD player & Lightscribe SuperMulti DVD burner
- 15-in-1 memory card reader, 2 USB, 1394, TV video
- ATSC-NTSC TV tuner with PVR, FM tuner, remote
- Sound Blaster X-Fi XtremeGamer
- Norton Internet Security(TM) 2008 – 15 month
- Microsoft(R) Office Home and Student Edition 2007
- HP wireless keyboard and HP wireless optical mouse

I like it so far. It is fast and does mostly what I want. My monitor is too old to play blurays so I may have to go ahead and upgrade it soon. I’m probably going to miss having two TV tuners but I’ll make do. Plus there is one piece that came with it that I’m not sure what it is. Overall I like it though. What is this?
