A simple HTPC build and also my first ITX. Some of these parts I had laying around but most were purchased new for this build. The Athlon X4 845 works well sitting at 65W. The Zalman cooler is too short though and ends up recycling hot air around the case. Which itself comes with no fans. To the inside of the case, I zip tied a 120mm fan which, I think, came off of an H100i. Now everything runs nice and cool. The Zalman cooler definitely needs a case with good air flow.
Initially, I was worried about cable management, but the Silverstone power supply comes only with the necessities. So it wasn't really an issues. I could actually have fit more in here.
The R7 250 is a great graphics card when the one you actually want to use hasn't arrived yet. It will be replaced with a GTX 960 in a few days. The lack of air flow in the case might be a problem for the 960.
The only real issue during this build was the X4 845 not working with the MSI motherboard without a BIOS update. It took me a lot longer than it should have to figure it out. About the processor: it actually scores higher benchmarks than my A10-7850K even though it has lower clock speeds. All while running much cooler. It's still not a powerhouse but I'm pretty happy with its performance so far.
This machine sits comfortably on a shelf under the TV where my Blu-Ray player used to live. After years of faithful service, I can't bring myself to throw it in the closet. I'll say goodbye, just not yet.
Edit: I threw a GTX 960 in there today. At load it runs around 80*C. Which is fine right now but may not be in the summer. So I've got some 120mmx12mm Scythe fans on order. I'm happy with this GPUs performance otherwise. I have another machine I built for gaming but if this was my only computer, I would be completely ok with that.
