This is a good deal for an HTPC build... no need for a gpu as this is a APU. It deals with intel offerings quite easily.

I think use this CPU for HTPC build is way over powered. You should be able to find AMD 65 W dual core CPU plus some low cost low power video card and serve the same purpose.- that way you can use smaller PSU and cut your electric bill.
If you do like this CPU- I do suggest pay a little more the AMD A8-3870K Unlocked- so you full use the potential of this CPU.

E450 is usually adequate for a HTPC setup that you won't try to game anything demanding on. Otherwise A4 would offer more power with lower power draw than A8.
