I can build my own desktops does anyone have a recommend build for a 1K budget or is that not profitable? I'm looking to try to make $25/day

This falls within 1K? How much money could I generate approx?

Be mindful of the physical location of those 4 slots, lest you have to use risers. Make sure the power supply has enough connectors for the cards you buy. Linux is worth considering for a dedicated mining box.

Getting the 5830's is the trick. If you can get them, they alone will cost you $600.

Depends if you want a mining-only rig, or a workstation that packs enough power to mine I would say.

Anyways, the only thing you really need to mine is a (several) high end AMD cards: the 58XX line, or the 69XX line; a PSU that can handle them, and enough air flow to handle the heat. The rest is irrelevant.

The rest is entirely up to you. If you plan to recycle your mining rig into a gamin rig, get yourself a nice CPU and a case to go with that. If not, get a celeron and a pizza case Cheesy

I really appreciate your fast replies, how did you come up with this? That seems like a crazy amount of profit for sitting on my ass..

Also does my internet speed matter much? I use comcast on cable so its pretty fast.

According to blockexplorer.com, you need to run on average 2,436,441,257,208,094 to win a block (50 btc).

You want to make $25 per day.  Say that's 1btc per day, given current mtgox price, with the extra $5 for overheads.

That's 50 days to solve a block.

So <bignum>/50/24/3600 = 564MHash/sec

So, if you build a rig capable of 564MHash/sec then you will average 1btc per day or $25 at today's prices and difficulty (although I'd suggest joining a pool to average out your btc rather than wait for the "big payout", given that these numbers are averages).

But... difficulty adjusts every 2016 blocks such that the eta of each block is ten minutes.  At the moment the network has more power than it "needs", so difficulty will adjust upwards in a week to a week and a half.

And... nobody knows what will happen with the value of btc.  If it keeps pace with difficulty then it's a wash.

As for what to buy, https://en.bitcoin.it/wiki/Mining_hardware_comparison

There is a profitability calculator for mining hardware available here

The mining client will not effect the speed of your cable internet as it uses very little bandwidth

Here is a good deal for the 5830 http://www.universalmania.com/ssproduct.asp?pf_id=1018416113
