It's the beginning of the month, which means that plenty of sites are renewing their line of contests. Here are a few of them:

The guys at XtremeComputing are giving away a complete micro-ATX-based PC, fully geared-out & even modded, to boot. They even lay it out with sound-dampening material, so that this rig would be a perfect HTPC. All you have to do to enter is send your answer to one simple trivia question to their contest email, along with your personal information. Sweet!

The O² crew have updated their monthly contest as well. This time, they're giving away a Spire RocKeteer VI - SLI Series SP-600W. The RocKeteer VI is powerful, modular, & looks pretty slick, too. Same deal as usual with O², just fill out their simple entry form, & you're entered.

Last but not least on the contest end of things today are the guys at TechwareLabs, who've teamed up with CoolerMaster for this month's giveaway. The lucky grand prize winner will walk away with a sweet case/PSU/cooling combo: an iTower 930, an iGreen Power 500W, & an Aquagate Viva. They're also giving away two runners-up prizes in the form of a Notepal P1, or an X-Craft 250. All you have to do to enter is post in their contest thread. Easy.
