And as for an esata port, I don't really know. this is my computer I am using as an HTPC : http://www.dell.com/us/dfh/p/xps-630/pd
I know it is kinda overkill but it's what I have right now.
Thanks so much for all the KILLER advice.
EDIT: also, I have Directv so I don't know how connecting via the cables would work as far as that option goes.
No. If you already have a gigabit router, you shouldn't need another switch. If not, you'd get a switch. Connect that to your internet modem/router, whatever, than plug your office computer into one of the ports. And into another port plug an ethernet patch cord that would run to one powerline adapter plugged directly into a wall outlet. On the other end you'd plug the other adapter into an outlet near where you want your htpc, and run an Ethernet patch cord from that adapter to your htpc. The powerline simply serves as a bridge in your ethernet network. As far as the devices plugged into the adapters know, they are plugged into a wired network.
If you got something like the netgear with a built in switch, you could also plug in your TV, blu ray player, or other ehernet enabled devices and have them all connected into your network.
In my experience powerline works very well when it works, but there are a variety of conditions in your home wiring that may prevent it from working, or working at a particular outlet or between a particular pair of outlets. You can try different outlets, but sometimes it's just a fail. More often than not it will work. Ethernet over coax may actually be more reliable, but is a little bit more complicated.
Edit, depending on how old your DirecTV setup is, you could be a prime candidate for ethernet over coax. Until recently, you needed two coax lines to each DirecTV DVR. Now with the SWM setup for DirecTV, you only need one, which would mean you have an unused coax line to your TV which is readily available for use as a ethernet connection without worrying about multiplexing. Also, Etherent over coax is actually what DirecTV uses for their Whole Home setup to connect your various DirecTV boxes to each other and to your internet connection. I think it's actually possible to piggyback your htpc off the DirecTV network if you have the Whole Home setup although i haven't actually tried it yet.
By the way, you'd probably also put your server or NAS in your office an plug it into the switch as well, and it would be networked to your htpc.
