How to find connected components of a random graph?

Need an expert to check my custom pc will work before i buy the components?

• Ive decided to build an HTPC/downstairs computer an i need someone with experience to check that all the components i have found will work. Im on a relativly low budget so i have tried to find some cheap but good components. My criteria for the PC is that it has to play Blu-ray, store files, be connected to a surround sound system, and run windows 7. The components i have chose are: Kingston 1GB DDR2 667MHz / PC2-5300 MEMORY CL5 1.8V NON ECC UNBUFFERED AMD Athlon II X3 445 3.1 GHz - Socket AM3 1.5 MB cache Retail Box Processor Western Digital WD2500AAJS 250GB Hard Drive SATAII 7200rpm 8MB Cache - OEM Caviar Blue Casecom MA-1199 Shiny Black MATX Tower Case - No PSU LG CH08LS10 8x BD-ROM with DVD±RW & LightScribe SATA Blu-Ray Drive - OEM Black ASUS M4A78-HTPC - Motherboard I need advice on a power supply I need to know if i have forgotten anything I need to know if there are any alternatives that may be just as good but cheaper I need to know if the components will work together (the case & moterboard are already purchased)

• Answer:

  Okay, here we go. Your motherboard choice is fine - I found a fairly decent review on it. That will cover the video and sound cards needs adequately: http://www.silentpcreview.com/article948-page1.html Memory - I'd go faster and larger. Using the onboard video is going to steal video memory from the system, so 2GB is safe - and fast. $39 2x 1GB Crucial 800 MHz http://www.newegg.com/Product/Product.aspx?Item=N82E16820148163 CPU - you can get by with much less and save a few $s. Nothing wrong with the Athlon II x3, but the x2 is more than adequate for HTPC use: $58 Athon II x2 245 2.9 GHz http://www.newegg.com/Product/Product.aspx?Item=N82E16819103687 Case is fine. Hard drive is a little on the small side, capacity wise, if you're going to be storing BD level video (which runs up to 20 GB/hr) Maybe this one instead? $70 WD 1TB Caviar Green http://www.newegg.com/Product/Product.aspx?Item=N82E16822136490 You will also need an OS (Windows 7 32-bit Home Premium would be a safe bet). $100 http://www.newegg.com/Product/Product.aspx?Item=N82E16832116752 USB keyboard & mouse - at least for setup. You could borrow that from another computer. Power supply needn't be much. This reliable $33, 350W one with a quiet fan is more than you'll need http://www.newegg.com/Product/Product.aspx?Item=N82E16817371003 You might want to consider a conventional Blu Ray player and a dedicated, very small HTPC such as this for video file playback: http://www.newegg.com/Product/Product.aspx?Item=N82E16856107072 That takes much less space near the TV.
