Depends on which one we're talking about, I own three, not including my servers.
My main computer is a Windows Vista Home Premium (Service Pack 2) that runs Windows XP Home Edition on the Oracle Virtualbox. The manufacturer is Acer, it's an Aspire M5630 model with an Intel Core 2 Duo CPU (E4500) at 2.19/2.20 GHz. It has 3.00 GB of RAM and it's a 32-bit OS. I play SMBX, make Adventure of Knux comics, and sprite on this computer, I also use it for social things regarding the Internet.
My secondary computer is my gaming PC, I don't have the specs right now, but I'll post them once I get them (I haven't been on the PC in 3 weeks).
My servers, or should I say my old XP, is a Windows XP Home Premium that I modified with 4.00 GB of RAM, it doesn't have a graphics card installed, nor a sound card, but it can run almost all of my servers. (Minecraft, Terraria, Garry's Mod, etc.). There isn't really anything special at all about it besides the fact that it was my first computer.
I used to be 8bitmushroom but not anymore.
