Building a PC for XBMC/VDPAU/1080p

I've always hoped XBMC would go full circle and evolve into something that was put into a standardised box that could have been fully supported with few driver headaches and every last Hz of power drawn from it effectively.

Doesn't look like that's going to happen now though, does it? So I'm thinking of buying/putting together a HTPC to replace the xbox. I've priced the following one up at abou £230, can anyone pick holes as to why I woudln't be able to use this to completely build a PC that was capable of getting 1080p HD out of XBMC?

• Extra Value Micro ATX 300W PSU - 20+4pin, 1x SATA 125004 50 in stock £14.10

• Arctic Cooling Alpine 64 GT Socket 754, 939, AM2, AM2+ Processor Cooler 150982 41 in stock £6.64

• Crucial 2GB Kit (2x1GB) DDR2 800MHz/PC2-6400 Memory Non-ECC Unbuffered CL6 Lifetime Warranty 139662 2 in stock £19.99
  

This might even be a useful reference point for others in the same boat as me. For what it's worth, savings can be made by removing the HDDs (and network booting) and by canaballising your old PCs for things like the DVD. This has some whistles and bells, such as a reasonably nice case, but generally it's as low as I could go!

Comments please?!

This is very similar to my setup. There is a minor problem with VDPAU and the 8200 - but there are work-arounds for it as well as one particular release that had a fix. Long term fix should be here soon anyway.

For reference here is my setup:

I actually ended up using an old HD and DVD drive... The retail box of the processor usually comes with a fan, unless you are buying that other one for noise reasons - because VDPAU barely uses the processor it never spins up very high.

I have a small suggestion. Don't buy an IDE drive, not so much because of the performance, but because IDE cables are a pain to deal with in small cases. I still use an IDE DVD-RW drive, but only because I had a spare one from a dead computer. Also I am very happy with my mATX Asus motherboard, but I have a P5N7A-VM.

Any specific comments about the sound from the Asus -VM motherboard? Has anyone got this and have it working, specifically in my case with optical out.

Have this board, but not in mini-ATX case (I've got mini-tower). Works good.

BTW, what are the problems with 8200 chipset with VDPAU? I haven't been running HD content yet (no use - my TV is still old resolution), but just curious... So far haven't seen any adverse effects on SD video.

I've recently upgraded my system based on an Asus P5N7A-VM. It works very well with XBMC, including optical SPDIF out (PCM). The GPU can run a little hot on this board if you use non stock Intel cooler and/or a cooler running on low speed. I'm contemplating putting a 40 mm fan on the GPU, since it idles at around 70 C.

See this thread:

Have you tried 'artbeats' and/or 'killa'? You *definitely* won't see it on SD video, only high bitrate 1080p. There are three work-arounds:

1. Select 1080i (doesn't really run in 1080i, it is really 1080p) this does not work for everyone.
2. Select 'auto' as resolution. Select 'test'. Restart XBMC. Select '1080p' as resolution'. Select 'test'.
3. Run with vdpau SVN 18670 - it has a 'safe fullscreen' option

Hopefully the fix with be in the main branch soon.

on IRC, also discussing how loud this would be because of the restricted airflow in the uATX case and no particularly quiet components.

I am running without a case fan with no temp. issues (~45C average).

My power supply fan is quite and the CPU fan never spins up much. However with no other noise in the room, yes you can hear it - but it quite acceptable.

I find when I'm using the HTPC there's a LOT of noise in the room The only thing is that I'm contemplating this box having a alter-ego as a NAS, though one that would generally only be accessed as a nightly backup and by multimedia played by itself and possilbly some old xboxes dotted around the rest of the house.
