I've got a nice small assortment of hardware on my Lan. First my DSL modem runs to a Linksys WRT54GS V2 (32m ram, 8mb flash) that has these devices connected to it:
My first Xbox (crystal) running an Ndure softmod with XBMC for media streaming.
My very customized xenon jtag 360 with 120gb hdd, no dvd drive and a giant heatsink on the GPU with a fan.
My home server (an old P4 with a small boot drive and big storage drive) which runs my torrents, newsgroups, ftp server, webserver, smb shares for all my media and a few other things.
and another 360, a banned xenon one I only hook up for gaming nights with friends.
On the other side of the house I have a WRT54GS v4 (16mb ram, 4mb flash) connected to the main router via WDS for clean routing. On that router:
An xbox with an ndure softmod I could to turn off for xbl access, this is used mostly for DLC work and collecting DLC when Xbox1 live was still up.
A tsop flashed 360 switched for PAL xbe regions also for DLC testing.
My main PC which is sadly just an athalon XP 2800+ with a gig of ram...it's a sad computer.
My main jtag 360, which is a Halo 3 edition Falcon which has a 250gb hdd in the halo 3 hdd case, and some custom cooling work done.
the PC and consoles both run on a 24" dell LCD monitor and a secondary monitor for the PC.
Finally I have a P3 1ghz with a few hdd's, old burners, and a sata card I use for diagnosing parts, doing repairs, modding, and to display video and images for when I need to do soldering and repairs.
My wireless devices are:
An old Sony Clie TH55 I use mostly for an Mp3 player, camera, address book, and notepad.
An original blue Nintendo DS with an NDSTT
My Hp Mini 311 netbook which is a little tricked out with custom webcam, tv tuner, extra ram and some other custom tweaks.
My wifes old Athalon XP laptop
My wifes newer Acer Turion laptop
Nintendo wii in the living room with a 160gb hdd connected via USB for games.
Yeah theres enough radio waves in my apartment outside the microwave to cook a turkey

I'm amazed InsaneNutter can even get on his wireless network with all those devices though.
