Always a risk buying PC parts on CL but so hard to pass up a good deal :)
Got the CPU, stock cooler, Mobo, Ram for $100. Guy also threw in an older HP with a valid windows sticker and an c2duo 8400 for $10 and a nice router for free) Just using the stock cooler, I was able to get stable OC at 4.4 at 1.25v. My own g3258 needs a higher voltage to be stable at 4.4. Kinda jealous, if it wan not such a pain, I'd switch out the chip with mine.
Now I know what cigarette smoke looks like on a motherboard :( PC Mate is a run of the mill board but I did get a nice stable OC, so no complaints. Also, no IO shield but from all the forum posts I read, no big deal other than ascetics.
Got the 750 ti for $90. The seller has flashed the bios to get it to use the full 60 watts. I guess they are typically throttled at 37 watts (http://cryptomining-blog.com/1014-how-to-increase-the-geforce-gtx-750-ti-power-target-limit). Benchmarks nearly matched my Radeon 7850. I am pretty impressed by that. http://www.3dmark.com/compare/sd/3042249/sd/2645820
The 750 ti also Allowed me to use my favorite budget PSU. The Antec VP 450 is well reviewed http://www.hardwaresecrets.com/article/Antec-VP450-Power-Supply-Review/1487 and falls into the revised tier list at tier 3, Still quality but not meant for serious OC or mad gaming. At only $34, I will always default to this PSU for low power builds.
No room in the budget for an SSD but that's OK. Fresh installs of windows loads in 15 seconds anyway.
Ram: Yeah, I know, 2X4 is better but this is what the CL guy had.
Case: Very cheaply made but still had good cable management and plenty of room for fans. Only comes with one. Looks pretty nice too if you don't want a window. Would look nice with two white from fans. $37 shipped. You get what you pay for. I'd use again.
Overall , I am pretty happy with the build. Plan on selling and having what ever profits go for my fundraising efforts for a charity Triathlon in July.
