I've been considering a PCH for a few weeks, but after doing some reading on here I think I can build a HTPC for not too much more than a PCH and 1TB drive. Main objective is 1080p playback, I also plan to use it for downloading content. It must be silent. I've quickly priced up the following on ebuyer. Gigabyte GA-MA78GM-S2H 780G OCZ 4GB (2x2GB) DDR2 800Mhz/PC2-6400 GOLD XTC Memory Kit Samsung SpinPoint F1 HD103UJ 1TB Hard Drive SATAII *32MB Cache* - OEM AMD Athlon 64 X2 4850e 2.5GHz Socket AM2 Energy Efficient 1MB L2 Cache I'm struggling with the Case and PSU. Antec NSK 2480 looks ok, although I have some concerns about the PSU noise. More importantly my flat has a shelf above the tv that is only 31cm deep. I could use a case that's a bit longer and have it hanging over the edge, but I'd prefer to use a shorter one that fits a bit better. Most cases seem to be over 40cm, and I'll need a few cm to get a power cable in. Excessive heat at the back is also a concern due to the lack of a decent gap away from the wall, although my 360 is quite happy there. Can anyone suggest a case and PSU combo that might work well in this situation?
