I just bought a HP 1170N Media Center PC at Circuit City. Why not get a Gateway? They didn't offer any 2005 Media Centers on their Web site (only through Best Buy) and the one model was too pricey for my budget. Dell? Too pricey (at the time I bought it). Tiger Direct? No 2005 versions available at the time. I also have quite a few HP products, including an iPaq, printer, digital camera, and a couple of old HP PC's. I've been really happy with all of the products, so I felt comfortable buying from HP.
My budget was about $1,000 and I desperately needed a new computer. We have taken more than 11,500 family photos, filled dozens of video tapes, and I wanted to be able to record and watch TV on my schedule. I was going to get a TiVo and another PC, but the Media Center made more sense. I priced out a HP computer with similar specifications, and it was nearly the same price.
The 1170n wound up costing $1,168.99 (after a $50 rebate). The features are better than I expected from a machine at this price:
Pentium 4 3.0GHz processor with Hyper-Threading
1MB Second Level Cache
512MB DDR SDRAM (can handle up to 4GB)
200GB Serial ATA
Radeon X3100 SE PCI-E graphics with 128MB DDR RAM
Dual-layer DVD +/- RW Drive
6 USB 2.0 and 2 Firewire ports
9-in-1 memory reader
So far I'm very happy and almost impressed with the product.
