Super basic build

[flibberdipper]

Alright, so I think have a new project that is going into long-term status. One of the lovely gents on this here forum (who will remain anonymous unless said person wants to be known) should be sending me a MicroATX LGA775 motherboard with a Celeron D. Now, before you bitch and complain, I'm NOT going to be gaming on this build. I will probably find a cheap Core 2 Duo on eBay, throw it in, and then get a low-profile graphics card. This is a cruise around the internet machine, with the occasional lightweight game. Now, I plan on using this case. I am not sure what PSU I will need for it though. It doesn't have to be extreme. The most it will ever really run will be a Core 2 Quad, Blu-Ray drive, (1) 1TB 2.5" 7200RPM drive, (2) 1TB 3.5" 7200RPM hard drives, and maybe a 750 or 750Ti. So it doesn't have to be anything special, maybe 350-500 watts. I would also like if it were semi- or fully-modular, while being fairly cheap (shoot for $50 USD being the limit). I'll also need some fans. I was thinking of the Arctic F8 (with PST) fans, since I have one in my grandma's computer and it is really nice. But I don't really know if there is anything much better for this application. So... Anyone have any ideas? Smaller builds like this are not my forte, so I have far less knowledge what the hell I'm doing.

Hmm... so I offered you a 775 board with an E8400 on it a while ago and that resulted in a huge fight and now you accept one with a Celeron D from someone else... mmmkay

 

Anyways, this a great deal going for these right now http://pcpartpicker.com/part/seasonic-power-supply-m12ii620bronze
