Re-purpose this PC as an HTPC?

Hey everyone,

I'm interested in building a HTPC but rather than build a completely new PC, I thought I could reuse my existing setup and simply buy a new case, Hard Drive and TV Tuner. Being rather new to this, I was hoping someone can help confirm if my components are a good match for one of the cases below & TV tuner and suggest anything I may be missing.

The main uses of the HTPC will be to record / watch cable TV & watch movies but I want to keep the case as small as possible since it will be in my entertainment rack.

Current component list:
1 x LIAN LI Lancool PC-K62 Black 0.8 mm SECC, Plastic + Mesh ATX Mid Tower Computer Case
1 x LIAN LI HD-322 Internal 2.5" HDD / SSD Mounting Kit
1 x ASUS P7P55D-E Pro LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
1 x EVGA 012-P3-1470-AR GeForce GTX 470 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
1 x XFX XXX Edition P1-650X-CAG9 650W ATX12V 2.2 / ESP12V 2.91 SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply
1 x Intel Core i5-760 Lynnfield 2.8GHz LGA 1156 95W Quad-Core Desktop Processor BX80605I5760
1 x OCZ Vertex 2 OCZSSD2-2VTXE60G 2.5" 55GB SATA II MLC Internal Solid State Drive (SSD)
1 x LG Black Blu-ray Disc Combo SATA Model UH10LS20 LightScribe Support - OEM
2 x G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM

Choice for cases:
#1 - LIAN LI Black Aluminum PC-C37U Micro ATX Media Center / HTPC Case (
#2 - SILVERSTONE Black Aluminum / 0.8mm SECC Grandia Series GD05B micro-ATX / Mini-DTX / Mini-ITX MB HTPC Case

1 x 2TB HD (any suggestions?)

TV Tuner: Ceton InfiniTV 4 Quad-tuner Card for Watching Digital Cable TV on the PC, PCI-Express x1 Interface

Thanks for your help!

  1. Both cases you've listed will only accept Micro-ATX motherboards and the ASUS P7P55D-E Pro is a full ATX board.

    Here is Newegg's list of compatible HTPC Cases.

  2. Thanks. I honestly want the smallest case possible & would even be up for changing out the motherboard if needed. If I decide to do that route, can you suggest an alternative that would work with one of the two cases above & my other components?
  3. Newegg doesn't carry a lot of micro-ATX 1156 motherboards, but this Intel LGA 1156 Intel H55 Micro ATX would probably work. You'd also need new RAM as this one only uses 1066/1333 DDR3. Lastly, if you decided to go with the LIAN-LI case, you'd also need a new low-profile graphics card.

    Of course, if you went with a new graphics card and made sure it was a single slot card, then other motherboards would work (the PCI-Ex1 slot wouldn't be covered).

  4. OK. Thanks for all your help. It seems like my only real option is to choose one of the larger cases unless I want to replace the majority of my parts.

    What would you do? Would it be better to build a new Ivy Bridge HTPC leveraging the micro atx setup or deal with the big case (that hopefully wont look & sound like a beast)? I would say my budget would be maxed at 1000 if I were to build a new PC.

    I would simply deal with the larger case. They're only about an inch wider and a bit taller than the Silverstone you listed.

    Height/Width/Depth of the Silverstone GD05B: 5.91"x17.32"x12.79"
    Height/Width/Depth of the Silverstone LC17-B: 6.7"x16.8"x16.8"

    However, if you're dead set on using a micro-ATX case, you certainly don't need an overly powerful system. I was going to mention that the components you have listed are serious over-kill for a non-gaming HTPC. The specs for my HTPC (see my signature block) are more than sufficient.
